Another year, another attempt to quantify the 9.2 quintillion outcomes of the NCAA tournament via my MDS Model. As I did last year, I've generated a composite set of rankings similar to what I used to sportsbet in Las Vegas.
I'm taking a composite of 4 different models, similar to what FiveThirtyEight does, and the same technique as last year:
- FiveThirtyEight (so I'm including a composite of a composite)
- KenPom (who's ratings are also included in FiveThirtyEight, so they're counted twice)
- Powerrank (created and maintained by Ed Feng)
- Massey Composite (another composite, this time spanning 68 rating systems)
I then use a weighted average of these 4 ratings that reduces outliers by weighting the ratings closer to the median higher. This smooths out the final Aggregate ratings that I then use to project the tournament. That being said, I have a good deal of trust in all of the above rating systems, so I wouldn't expect anything too crazy outlier-wise.
Note: For simplicity, I've taken the highest rated team in each play-in game and included them.

Some quick reactions:
- North Carolina seems to have the toughest route, but also has the lowest rating in my model of the 1 seeds. These two combined factors result in the lowest probability of the 1 seeds of reaching the Final Four (32.56%)
- Of course Virginia has the lowest chance of winning their first game out of all the 1 seeds (97.08%)!
- The fan base that has the best right to complain is Michigan St: they're #4 overall, yet get #2 Duke in the Elite Eight, and only have a 27.24% chance of reaching Minneapolis
The top 12 teams in the tournament are as follows:
Rank | Team | Rating |
1 | Virginia | 95.38 |
2 | Duke | 94.78 |
3 | Gonzaga | 94.23 |
4 | Michigan St. | 93.03 |
5 | North Carolina | 92.71 |
6 | Michigan | 91.94 |
7 | Tennessee | 91.40 |
8 | Kentucky | 91.05 |
9 | Texas Tech | 90.22 |
10 | Purdue | 89.35 |
11 | Virginia Tech | 88.43 |
12 | Florida St. | 88.10 |
5 of these top 12 are ACC, which is a real testament to the strength of the conference. The Big 10 has 3, the SEC has 2, and the Big 12 only has 1.
A word of caution about straight up copying the above: in most pools you want to gauge "contrarian" picks relative to the overall pool. My suggestion would be to use the above probabilities as a guide ("I'm just a guide"), and make contrarian picks that have a good chance of happening (like picking a champion that has solid odds but isn't necessarily the favorite).
