First of all, any title game that ends up with a 37-point margin is by definition an aberration as far as I'm concerned. No way should the game have been that non-competitive. I certainly wasn't expecting anything like that. So a lot of it probably can't be explained away logically.
I can only make a couple of points that probably impacted only around the margins.
First, on the season, your average night from 3-point land was 5-for-15. So in that regard, I'd say your 3-for-17 showing in the title game was far less an aberration than the 12-for-22 performance you had in the semi-final. I'd say that previous game was the outlier in that one area.
And second, despite the fact that your team was a bit more talented in terms of ratings, especially amongst your starting five, I still felt fairly confident heading into the title game because I felt I had a significant IQ advantage over your team.
Looking at minutes played in the title game, the time-weighted average IQ (offense and defense) for your Stanford team was 9.19 (that's assigning 12 for A+, 11 for A, 10 for A- and so on), whereas Michigan State's was 10.77. So I had more than a full letter grade-and-a-half IQ advantage over your squad. I think that's why I won, but nothing will ever adequately explain the margin.
