Michigan State versus UConn in the Sweet 16, by the numbers

On Friday evening in our nation's capital, two storied programs will meet in the Sweet 16 for the right to advance to the Regional Final on Sunday. The No. 3-seeded Michigan State Spartans will tangle with the No. 2-seeded UConn Huskies.

Sunday will mark the third all-time NCAA Tournament meeting between the Spartans and Huskies. In 2009, Tom Izzo and company defeated UConn in the national semifinal game at Ford Field. It was the only loss that UConn coaching legend Jim Calhoun ever suffered in his three trips to the Final Four.

Five years later, UConn exacted revenge on Michigan State as the No. 7-seeded Huskies overcame a nine-point second-half deficit to upset the Spartans in the 2014 Regional Final. A little over a week later, UConn hosted the National Championship trophy.

UConn is currently a narrow 1.5-point favorite against MSU, which is just barely below the historical average of a two-point spread in No. 2 versus No. 3 seed games in the NCAA Tournament. Based on this spread, the Huskies have about a 56% chance to defeat the Spartans.

But what are the relative strengths and weaknesses of each team? Where can the Spartans expect to carve out an advantage and where do they need to take particular care? Let's take a closer look at the two teams as well as the other two teams in the East Region (Duke and St. John's) from the view point of the four factors of basketball success and tempo adjusted efficiency.

Overall Efficiency

Figure 1 below provides a visual summary of the adjusted offensive and defensive efficiencies for the four remaining teams in the East Region of the 2026 NCAA Tournament. These values are tabulated by Ken Pomeroy and were as of the Monday following Selection Sunday. For reference, the efficiencies of each Big Ten team are also plotted.

Figure 1: Pre-NCAA Tournament Kenpom adjusted offensive and defensive efficiencies for the four remaining teams in the 2026 East Region as well as the members of the Big Ten.

For the four teams competing this weekend in Washington D.C., the data point labels also contain the numerical ranking for each team both on offense (the first number) and defense (the second number). 

For example, Michigan State ranked as the No. 24 team on offense and the No. 13 team on defense as of March 16.

The overall Kenpom efficiency margin (which can be used to accurately project point spreads) is defined as the difference between offensive and defensive efficiency. Graphically, the efficiency margins increases diagonally from the lower left-hand corner of the graph to the upper right-hand corner.

As Figure 1 shows, Duke is the most efficient team remaining in the East Region. This is not a surprise considering that the Blue Devils ended the regular season as the top team in Kenpom efficiency margin and earned the No. 1 overall seed in the Big Dance.

Also note that the Michigan Wolverines have an efficiency profile that is almost identical to that of Duke.

As for the rest of the East Region participants, Michigan State, UConn, and St. John's are all clustered together in a very similar region of the graph. The three schools have virtually identical defensive efficiencies which rank No. 11 (UConn), No. 12 (St. John's), and No. 13 (Michigan State) in the country.

The primary difference between the three schools is that the Spartans grade out with the best offense (No. 24). UConn is next with an offensive rank of No. 29 while St. John's checks in with the weakest offense in the region at No. 44.

Overall, MSU (No. 9) has a slight edge in efficiency margin over UConn (No. 10) and St. John's (No. 17). Based on Kenpom, Michigan State should be a very slight favorite (-0.3) to beat UConn on Friday night. MSU also projects to be 1.5-point favorite over St. John's and a seven-point underdog versus Duke.

For reference, both UConn and St. John's most resemble Big Ten foe Nebraska in regards to offensive and defensive efficiency.

Shooting

Now let us dive a little deeper in the data to understand the relative strengths and weaknesses of each team through the lens of the four factors of basketball success which are shooting, turnovers, rebounding, and free throw rate.

Figure 2 below summarizes the shooting prowess of the same group of 21 teams highlighted in Figure 1. The effective field goal percentage for each team is plotted on the x-axis while the defensive effective field goal percentage allowed is plotted on the y-axis.

Figure 2: Summary of the offensive and defensive effective field goal percentage for the four remaining teams in the 2026 East Region as well as the members of the Big Ten.

Recall that effective field goal percentage is a weighted average of two-point and three-point percentage to normalize that expected number of points per attempt.

Duke and UConn grade out as both very good shooting teams as well as teams that are very good at defending shots. They both rank in the top 40 in shooting and in the top 15 in defending. These numbers are not as strong as the values posted by Michigan, but they are stronger than other Big Ten teams such as Nebraska and Illinois.

The Spartans grade out as the third best shooting team in the regional (No. 70 nationally) ahead of only St. John's (No. 193). Overall, Michigan State is the weakest team in the region (No. 53) when it comes to defending shots.

For reference, the profile for St. John's is similar to a team that shoots like Washington overall but defends shots like Nebraska.

But let's dig a little deeper. Figures 3 and Figure 4 below break down the shooting statistics by two-point shooting and three-point shooting using the same format as Figure 2.

Figure 3: Summary of the offensive and defensive two-point field goal percentage for the four remaining teams in the 2026 East Region as well as the members of the Big Ten.

Figure 4: Summary of the offensive and defensive three-point field goal percentage for the four remaining teams in the 2026 East Region as well as the members of the Big Ten.

The two-point shooting data largely mirrors the effective field goal percentage data in Figure 2. On offensive, Duke (No. 8) is the most efficient team closer to the hoop, followed by UConn (No. 30), MSU (No. 91), and St. John's (No. 198).

Defensively, UConn (No. 12) is the best defensive team on two-point shots, followed by Duke (No. 20), St. John's (No. 39), and Michigan State (No. 46).

The story is a little different from deep. Michigan State is actually the best overall three-point shooting team in the regional at No. 44 nationally at just over 36%. UConn (35.2%, No. 107) and Duke (34.6%, No. 143) are both outside the top 100 while St. John's (33.2%, No. 217) is not even in the top 200.

That said, both UConn and Duke rank in the top 25 in three-point shooting defense and St. John's is in the top 40. Statistically, UConn and Duke grade out similarly to Nebraska and Illinois. St. John's defends three-point shot similarly, but shoots more like Nebraska or Rutgers.

It should be noted that the Spartans are also on a hot streak when it comes to outside shooting. Michigan State has shot over 40% from deep in each of the last three games. In order for the Spartans to have a successful trip this weekend, continued strong outside shooting will likely be necessary.

But how reliant are the four teams in the East Regional dependent on the three point shot? Figure 5 below summarizes both the offensive and defensive three-point shooting rates, which is defined as the percentage of total field goal attempts come from behind the three-point line.

Figure 5: Summary of the offensive and defensive three-point shot rate for the four remaining teams in the 2026 East Region as well as the members of the Big Ten

None of the four East Regional participants are particularly high-volume three-point shooting teams. Duke takes the most deep shots (44.4%) but is still outside of the top 80 nationally. The Huskies takes just over 40% of their shots from deep (No. 164) which is still more than MSU (36.4%, No. 241) or St. John's (33.7%, No. 299).

Interestingly, teams tend to take a lot of three-point shots against both Michigan State (45.9%) and Duke (45.5%). Perhaps this indicates that both teams make it difficult to get into the lane on defense.

On the other side of the coin, the opponents of both UConn (36%) and especially St. John's (33.7%) tend to take fewer three-point shots overall, perhaps due to an emphasis in running teams off from the three-point line. These values are smaller than any Big Ten team, which suggests a slightly different style of defense played by UConn and St. John's.

The Other Four Factors

While shooting is the most important factor in winning or losing basketball games, it is also important to maximize the total number of attempts at the basket and to get as many free opportunities to score from the charity stripe as possible. That is where the remaining four factors come in.

Figure 6 below shows the summary of the offensive and defensive turnover rates from the same set of teams highlighted above.

Figure 6: Summary of the offensive and defensive turnover rate for the four remaining teams in the 2026 East Region as well as the members of the Big Ten.

When it comes to turnovers, St. John's is the cream of the crop in the East Region. Similar to Nebraska's profile, the Red Storm are in the top 60 in taking care of the ball and the top 40 in creating turnovers.

Duke is mediocre in this category. The Blue Devils rank right around No. 100 nationally in both the offensive and defensive turnover categories. Duke most resembles Penn State in this regard.

UConn creates about the same number of turnovers as Duke does, but the Huskies tend to turn the ball over a lot. UConn is ranked just No. 188 in turnover rate on offense, similar to Minnesota.

But Michigan State is, by far, the weakest team in the region when it comes to turnovers. The Spartans turn the ball over more than UConn does (No. 207) and to make matters slightly worse, MSU is near the bottom nationally in creating turnovers (No. 299).

Turnovers have been a problem for the Spartans in isolated games this year. That said, MSU has been better recently at taking care of the ball. The Spartans' average turnover rate is just 15.6% since Feb. 1. Over the first three months of the season, the average rate was 18.2%. That said, turnovers is one of the main reasons that the MSU's second round win over Louisville was as close as it was.

As for UConn, the Huskies' issues with turnovers seem to be getting worse and not better as the season has progressed. UConn's average turnover rate is 18.3% since Feb. 1, and the rate was over 19% in eight of the Huskies last 14 games. It was just 16.2% in the first three months of the season. 

In these trends continue and if the Spartans can commit fewer turnovers than UConn, it will be an important step towards victory on Friday night for the Spartans.

Figure 7 below shows the summary of the offensive and defensive rebounding rates from the same set of teams.

Figure 7: Summary of the offensive and defensive rebounding rate for the four remaining teams in the 2026 East Region as well as the members of the Big Ten.

As Figure 7 shows, all four teams in the East Region are very good offensive rebounding teams. All four teams rank in the top 35 nationally, but Michigan State (No. 9) and Duke (No. 5) are both elite offensive rebounding squads.

Defensively, MSU (No. 1) and Duke (No. 9) are also elite, but UConn (No. 93) and especially St. John's (No. 172) are more pedestrian on the defensive glass. The two Big East teams resemble Washington and Maryland statistically when it comes to the boards.

In contrast to turnovers, rebounds are an area where Michigan State should be able to carve out an advantage over any of the three other teams in the region. That advantage may not be huge, but a couple of extra shots can be the difference between advancing and going home.

Finally, Figure 8 shows the summary of the offensive and defensive free throw rates from the same set of teams.

Figure 8: Summary of the offensive and defensive free throw rate for the four remaining teams in the 2026 East Region as well as the members of the Big Ten.

This is an area in the data where there is a clear difference between the four teams in the East Region.

Duke is really good at not fouling. The Blue Devils rank No. 2 in the country in defensive foul rate behind only Illinois. Note that the Spartans have faced four other teams in the top 10 in this category: North Carolina (No. 3), Oakland (No. 5), Purdue (No. 7), and Nebraska (No. 8).

But the Blue Devils' ability to draw fouls is average at No. 111.

St. John's is a mirror image of Duke. The Red Storm tend to draw a lot of fouls (No. 35 nationally) but they also commit a moderate amount themselves (No. 99). St. John's looks a little like USC from a fouling point of view.

Michigan State is fairly average in both categories. The Spartans generate a moderate number of fouls (No. 152) but generally avoid fouling their opponents too much (No. 81).

UConn appears to have a major problem with fouls. The Huskies both commit a lot of fouls on defense (No. 303) and they struggle to generate free throw attempts for themselves on offense. 

Even when UConn gets to the foul line, they only shoot 72.2% (No. 200 nationally) from the line. By contrast, as a team MSU shoots 76.5% (No. 40) from the free throw line.

Add it Up

When all this data is taken together the key points for the Spartans' Friday night clash with UConn and the potential Sunday matchups start to take shape.

Against UConn, the Huskies are likely to be the better shooting team overall. However, there may be the opportunity for Michigan State to carve out a nice advantage from the three-point line. Depending on the flow of the game, it might make sense for MSU to take a few more deep shots that usual.

That said, there is reason to believe that the Spartans can generate more shots from the field than UConn based on potential advantages in both turnovers (if recent trends continue) and on the boards. 

Even if the Spartans are only able to muster a draw in turnover and rebounds, there is a strong possibility that MSU will be able to significantly outscore UConn from the free throw line. This could be the hidden factor that will decide the outcome of the game on Friday night.

If MSU can defeat UConn and draws St. John's on Sunday, there is good chance that MSU can outshoot the Red Storm from the field and there is an even better chance that the Spartans can outrebound them.

However, the Spartans are at a potential disadvantage against St. John's in the areas of turnovers and free throw shooting. In this potential matchup, taking care of the ball and avoiding fouls would be critical.

If Michigan State were to draw Duke in a Sunday clash, the Spartans would really need to bring their A-game overall. On paper, rebounding is the only area where MSU is better than Duke and that advantage is relatively small. The Spartans would need to win this battle and they would also need to shoot the ball a lot better than the 32% effort at the Breslin Center back in December.

That said, the majority of the statistics shown above were generated when Duke was fully healthy. Starting point guard Caleb Foster (who scored 12 point at Breslin Center last December) is not expected to play this weekend and starting center Patrick Ngongba has just returned from injury.

It is reasonable to assume that the version of Duke that will play in D.C. this weekend is not quite as strong as the numbers above imply. 

If this is the case, there is a clear path for Tom Izzo and the Spartans to defeat UConn and then either Duke or St. John's to once again advance to the Final Four next weekend in Indianapolis.

Dr. Green and White Helps You Fill Out Your Bracket (2026 Edition)

In my opinion, the middle of March is the absolute best time of the year. Over the past two weeks we have witnessed the exciting conclusion of several regular season conference races, followed by 31 conference tournaments. This past weekend, the full 68-team NCAA Tournament bracket was released. Sports fanatics are on the brink of Madness. Who will play the role of Cinderella in the story of the 2026 tournament? Will any survive to reach the second weekend? Which four teams will advance to Indianapolis on that first weekend in April? Which lucky team will end up cutting down the nets?  Over the years I have developed a set of analytics and computational tools to gain a better understanding of the mathematical underpinning of the NCAA Basketball Tournament. My methodology has a solid track record of correctly identifying upsets and sometimes doing more than that. In 2023, I used data to correctly predict that No. 4 seed UConn would win the National Title. There is no foolproof way t...

2025 College Football Analysis, Part Two: A Deep Dive into MSU's Schedule

In part one of this year's math-based preseason analysis of the college football season, we looked back at the 2024 season. Through that analysis, we learned about the historical accuracy of preseason polls (plus-or-minus 25 positions) and regular season win totals (plus-or-minus 2.5 wins). We also explored the impact of changes in ability, schedule, and luck. Now it is now time to shift focus to the 2025 season. Over the years I have developed and refined a way to simulate the entire college football season using schedule information and preseason rankings as the only inputs. I will soon go through the full details of what I learned from this exercise.  For today, I will focus exclusively on what it says about the Michigan State Spartans. We will take a close look at the Spartans' 2025 schedule from three different points of view. Opponent Overview The best place to start this analysis is with the simulation's inputs.

After a strong swing through the state of Indiana, March beckons for Michigan State basketball

I have a bit of a confession to make. Back in December when I was reviewing the overall Big Ten schedule for the Michigan State Spartans, I noticed the back-to-back games at Purdue and at Indiana at the tail end of the conference campaign.  The games were spaced just three days apart, and the Spartan have struggled noticeably in both buildings historically. Outside of possibly the west coast trip in January, this two-game stretch looked like the most subtly challenge portion of the entire schedule. I believed that just getting a split in two games would be a success But the Spartans surprised both me and the college basketball world be rising to the challenge and winning both games. Other Big Ten teams were not as fortunate this weekend as both Purdue and Illinois picked up an additional loss. Table 1 below shows the updated enhanced Big Ten standings following the weekend's action. Table 1 : Enhanced Big Ten standing as of March 2. Michigan's win over Illinois on Friday night ...
