Some quick thoughts as I compare my rankings to everyone else's:
1) Virginia is a consensus 2 seed
I'm okay with this, even though I have them on the 4 line, the lowest of anyone. My simple retort is one of mathematics. The ACC is deep and I expect several mid-table teams to pick off games against UNC/Duke/Virginia. Are there enough wins to go around to create 3 ACC teams on the top 2 lines? I think Virginia will absorb a couple more body blows in ACC play than the other two teams, and it'll be worth a seeding line or so in March.
2) The Big East
The 2nd highest BEast team on the Matrix is Butler as the last 6 seed, then G'town as the first 7 seed. If the BEast is as good as I think it is....there's no way their 2nd best team is only the last 6 seed. They'll be much higher. I made my bet on Georgetown as that team. So I think the Matrix is wrong....but I see why the Matrix is off here. People can't make up their mind as to who Big East #2 is, as Butler and Georgetown have a few 4 seeds and Xavier has a few 5s.
3) San Diego St as a consensus 9 seed, 5 seed here
I feel like SDSU (and Boise) will run away from the rest of the league, and the committee has given 5 seeds (or similar seeds) to teams who run away with conferences like the MWC. Feels more right than not to start SDSU high.
4) The A-10
The Matrix has 3 A-10 teams in the bracket, but all in the 10-11 seed range. Its best team on the 10 line? That seems highly unlikely to me. This seems to be another case where a lack of consensus hurts the Matrix performance - there seems to be a lot of disagreement on whether any single team can make the tournament. URI and Dayton are out of several brackets.
5) I know it's hard to do in the preseason, but go look at Wichita's last 2 regular seasons and their current starting backcourt. They just can't be below the 3 line, right?
6) The Pac-12
One place I might be too aggressive is on the Pac-12. I count only 2 sure bets (Cal and Arizona). Well, Utah too, but a step behind. If the league doesn't supply quality wins, can they get a 3 and 2 seed, respectively? Maybe. But the degree of difficulty might be high.
