Hoop Odds Update: Analyzing the Home Stretch

Breathe, MSU fans.

The emotional rollercoaster that is Michigan State basketball continues to chug along. Up until February, the Spartans seemed poised to challenge for yet another Big Ten title. But then the bottom dropped out to the extent that there were whispers that the Spartans were attempting to play themselves onto the NCAA bubble.

On Saturday, Michigan State appeared sharp and focused for the first time in weeks, and the Spartans led the conference leading Purdue Boilermakers for almost the entire game. In the final minute, it looked as though the bottom might drop out again. Fortunately, Tyson Walker had other plans, and the Spartans emerged with a desperately needed, possible season changing, victory.

In times like these it is important to remember that a team is seldom as bad as their last big loss (such as at Iowa) and seldom as good as their last big win (such as versus Purdue). The truth is likely somewhere in the middle. That said, it certainly was nice to see the Spartans flying around on defense, playing with passion, and making shots on Saturday. 

The question now is whether the Spartans are now once again on the rise and building towards a traditional March surge or if the win over Purdue was simply a temporary blip. Either way, with 10 Big Ten wins now secure and another high-quality win on the resume, I am confident that the Spartans will be breathing easy on Selection Sunday. Michigan State is now playing just to get better and to try to improve their seeding for both the NCAA and Big Ten Tournament.

With just one week of conference play remaining, let's take a quick look at the current Big Ten race and how it will impact Michigan State's post season.

Big Ten Race

Tables 1 and 2 below show the enhanced Big Ten standings and the updated odds for the Big Ten regular season race.

Table 1: Enhanced Big Ten standings as of Feb. 28, 2022

Table 2: Updated odds to win or share the Big Ten title and the win distributions for those winning teams.

Michigan State is currently in a tie with Iowa for fifth place in the conference. Rutgers is a half-game back and Michigan is a full game back of the Spartans and Hawkeyes.

As for the race for the regular season title, Coach Tom Izzo should expect a nice fruit basket in the mail from Coach Greg Gard and the Wisconsin Badgers, as Michigan State's win over Purdue this weekend all but sealed a championship in Madison. Wisconsin just needs one more win to secure the title. 

The Badgers can earn at least a share of the title if they can beat Purdue at home on Tuesday night. If this happens, Wisconsin will almost certainly claim a solo title, as they close out the season with a home game against cellar-dwellers Nebraska on Sunday.

If Purdue beats Wisconsin, the Boilermakers will earn a share of the title with a win against rivals Indiana on Saturday. Illinois can also earn a share if the Illini can win their final two home games against Penn State and Iowa this week.

Michigan State's Final Stretch

With just three games remaining, the projected point spreads and win probabilities for the Spartans are as follows:

  • Tuesday, March 1: MSU (+3.5) at Michigan. Odds to win = 36.5%
  • Thursday, March 3: MSU (+5.5) at Ohio State. Odds to win = 29.3%
  • Sunday, March 6: Maryland at MSU (-7.4). Odds to win = 76.8%  
The resulting odds for any final record between 10-10 and 13-7 is then summarized below in the Big Ten win matrix

Table 3: Updated Big Ten expected wins and win distribution matrix as of March 1.

Michigan State's current expected win total is 11.43, which means that it is close to 50-50 as to whether the Spartans will win 12 games or more. The math actually says that the ratio is 45-to-55. Another way to look at this data is that a final record of 11-9 is the most likely single result (44.4 percent), but the odds to finish with a record of 12-8 or 13-7 is almost identical (45.1 percent).

Big Ten Tournament Breakdown

With the regular season winding down, the focus for the final week will almost entirely be on positioning for the Big Ten Tournament. As of Tuesday morning, there are 15 regular season games remaining, which implies that there are still 32,768 potential outcomes. Table 4 below summarizes the updated Big Ten Tournament seeds matrix, including the odds of Michigan State's first tournament opponent.

Table 4: Big Ten Tournament seeding odds as of March 1, 2022.

Based on the results over the weekend, Michigan State's position has improved noticeably. The Spartans are projecting as the No. 6 or the No. 7 seed. In addition, the most likely first round opponent for Michigan State is now Maryland (32 percent) with Penn State (19 percent), Indiana (16 percent), and Northwestern (11 percent) as the next most likely.

With only three games remaining, there are only eight total scenarios left for the Spartans. In one of those scenarios, Michigan State wins all out to finish at 13-7. In another scenario, the Spartans lose out to finish at 10-10. There are then three ways each to finish the regular season at 11-9 and 12-8. 

I ran an additional set of simulations on each of these eight scenarios to better understand Michigan State's final placement in the Big Ten Tournament. Table 5 summarizes the results of these simulations.

Table 5: Odds for MSU to earn each Big Ten Tournament seed and the most likely first tournament opponent based on the eight remaining scenarios

As Table 5 shows, Michigan State's final record should be a clear indicator of Spartans' Big Ten Tournament seed. If Michigan State wins out, there is a very good chance that the Spartans will sneak back into the top four and be able to earn a double bye. In this scenario, Michigan State would finish in no worse than a tie with Ohio State and would also own the head-to-head tiebreaker. That said, the Spartans' most likely first opponent in Indianapolis would then be No. 5 seed Ohio State.

The only way for the Spartans to slip to the No. 5 or No. 6 seed is if Iowa wins out (including road wins at both Michigan and Illinois). So, in order for Michigan State to maximize the possible seed, it is reasonable for MSU fans to root against Iowa.

If Michigan State can win two of the final three games to finish 12-8, the Spartans will most likely earn the No. 6 seed. The most likely way for this to occur would be for Michigan State to beat Michigan and Maryland, but to lose in Columbus. In this scenario, both Iowa and Rutgers are problematic from a tie-breaker point of view. Rutgers travels to Indiana on Wednesday night. A win by the home team would help MSU for seeding purposes.

If the Spartans are only able to win one of the final three games and finish at just 11-9, the No. 7 seed in the Big Ten Tournament will be the most likely result. In many of these scenarios, the Spartans end up either behind or in a tie with Rutgers and Iowa in the final standing. Michigan State in 0-2 against those teams head-to-head this year and thus the tiebreakers would not help the Green and White.

Finally, if the Spartans somehow fail to win any more games this regular season, the No. 8 seed becomes the most likely outcome. Hopefully, it will not come to that.

That is all for today. Until next time, enjoy, and let's get that win over the Wolverines tonight. Go Green.

March Madness Analysis: Did the Selection Committee Get it Right in 2025?

I will be assembling my "usual" stats-based analysis of the bracket, complete with picks a little later this week (but before Thursday). For now, I had some thought on the bracket. In general, MSU's draw is about as good as fans could expect. I will go into more detail on that later. As for the job that the committee did... I am far from impressed. Once again, there are multiple errors in team selection, seeding, and bracketing as a whole. Let's look at each one in turn. Did the Committee get the right 68 teams? More or less. This is the area where I am the least concerned. As I mentioned yesterday, my metrics had UNC safely in the field and not even in the First Four, but I swapped them out for WVU at the last minute. UNC's single Q1 win gave me too much pause. I felt slightly vindicated when UNC made it.  My biggest beef is with Texas making it in at 19-15. That's just too many loses. Yes, they had 7 Q1 wins, but that also had 5 loses outside of Q1 and an ov...

Dr. Green and White Helps You Fill Out Your Bracket (2025 Edition)

For my money, we are all of the cusp of the best three weeks of the entire year. We just wrapped up two weeks of conference tournaments, but those were just an appetizer to the main course that is yet to come.  The powers that be gave us the menu on Sunday evening for the feast that is to come. Now it is time to enjoy a brief break and palette cleaner before we all make our selections. But what shall we choose? Which tasty little upset looks the best in the first round? Which teams are most likely to be sweet in the second weekend? Which quartet will comprise the final course? 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 win the National Title. There is no foolproof way to dominate your...

2024 Week Eight Preview: OK Computer

Playing the first game after a bye week is like waking up from a nap. It is a little tough to predict how the body will respond. If a nap comes at just the right time and lasts for just the right length of time, it can be very refreshing and rejuvenating. But sometimes waking up for a nap can be rough. It can cause a disorienting, groggy feeling like suddenly two plus two equals five and that down is the new up. Based on the way the three weeks prior to the bye week went, last week's break at the midpoint of the season came at exactly the right time for the Spartans. Facing one top five team is challenging enough. Facing two top five teams on consecutive weekends including almost 5,000 miles of travel is something else entirely. But how will the rested Spartans look on the field come Saturday night? It is hard to predict what we are going to get. It is the classic "rest versus rust," million dollar question.  I prefer to be optimistic and to believe that the Spartans will...
