Nicely done on the prediction!
On a side note, here is a nice way to bet conferences in the dance (I did this last year with a Big 10 homer and won, we are rematching again this year):
Pick a conference and you get all the points for the teams in that conference. Points are allocated as follows: 1 point for every game they win OVER their seed. They lose a point for every game UNDER their seed. Each team gets none if they play to their seed. Sounds confusing but it is cake. Example: ISU as a 3 seed should play to the sweet 16 to "play to their seed". If we lose before that, we lose a point for each game under. If we win the sweet 16, we get a point for that game because we were under seeded to the 2-seed, and one point for any game we win after that.
If you pick the big 12 and you buddy picks the big 10, you should be sitting pretty. It is a fun way to have skin in a ton of games and be cheering for all the other big 12 teams. We had a lot of fun with it last year and are going to do it again this year.
