Sean Forman Sims the NCAA Tournament

Posted by Sean Forman on March 16, 2009

Sean Forman of Baseball-Reference.com makes a guest appearance to present the results of his annual NCAA Tournament simulation. --JK

As I've done for the last six years, I've relied on a little bit of computer science to fill out my NCAA tourney pool. I have two young kids at home, a baseball site to worry about, and I've watched zero NCAA basketball games this year, so using my own scouting and intuition is obviously out.

What I do instead is rely on a rating service and simulation to compute the best (in this case, most likely) bracket to occur. Invariably, this leads to a boring bracket, but you'll find in the long run that better teams win more games in the NCAA tourney. Doing the simulation also provides some interesting answers to questions like "Which low seeds are most likely to make the Sweet 16?", and it presents it all in terms of probabilities.

The Method in a Nutshell

I've given several talks on this method (slides) if you are interested in a more detailed treatment. First, I use the Sagarin College Basketball Ratings Predictor to determine the relative strength of each team. These are Sagarin's most accurate ratings for predicting games and inherently take into account things like margin of victory, strength of schedule, game location, etc. I then, essentially, play the 63 games in the tourney (I assume the better play-in team wins) and repeat the process over and over (I stop at 1,000,000 simulations). Along the way, I track who wins each game and summarize the results.

What I Don't Do

There is no consideration for things like injuries, momentum, location of tourney games, etc. This is purely based on the complete season results for the teams. So if a team lost their star player in the final seconds of the conference championship game to a knee injury, this system won't take that into account.

The Results

As I said earlier, this system is going to present boring results: no #13 seeds in the Sweet 16, and no #6 seeds in the Final Four. In fact, just using the Sagarin Predictor to create your bracket will give you a similar (but not the same) outcome. For me, the interest is in the probabilities. For example, last year, I had Davidson losing in the first round, but they were a 20% shot to make the Sweet 16. Not bad for a #10 seed.

This first chart shows the percentage of times each team lost in a particular round ordered by their Sagarin Predictor rating. Notice that Gonzaga -- who Sagarin has as the 6th best team -- is not the sixth most likely to win the tourney thanks to their #4 seed and the hard road (through UNC) the Selection Committee gave them.

        Gonzaga              (  6 - 0.057) 

While the #1 or #2 seeds are the best bets to make the Final Four, the probability of the Final Four being all #1's or #2's is actually quite small. Figuring out who not to pick is, of course, the hard part.

Prob. of only #1 or #2 in Final Four =
(.359 + .135) * (.336 + .272) * (.368 + .294) * (.439 + .105) = 11%

 9-Tennessee            ( 30 - 0.112)
 8-Oklahoma State       ( 31 - 0.105) 

In general, #8's and #9's are really bad Cinderella picks because (1) they are playing a comparable team in the first round and (2) they are virtually guaranteed to play one of the five best teams in the second round. On the other hand, #6's and #12's only have to get past a #4 seed, who has a significant chance of being upset in the first round.

3 Responses to “Sean Forman Sims the NCAA Tournament”

  1. Neil Paine Says:

    What's remarkable is that the only places where our systems differed were Arizona State's Elite 8 chances (I had ASU beating the 'Cuse & OU), UCLA vs. Duke in the Sweet 16 (I had the Bruins pulling the upset), and the Memphis-UNC title game (I had Memphis winning it all). Not bad for two fairly different statistical methodologies...

  2. Sean Forman Says:

    Neil,

    Arizona State is probably the better team to get into the Elite 8, but since they have a harder row to hoe, they are a worse bet to make it (IMO) to that round. I have to say that I think the way yours provides the score is pretty sweet.

  3. Why Simulate Says:

    Sean,

    Why actually simulate the games? Can't you just figure out what would happen in an infinite number of simulations through simple multiplication and addition of the different probabilities of making a round/facing a team/beating that team? Is it because simulation lets you look at individual matchups more easily?
