I last updated my bracket prior to yesterday's games, but I think you're pretty close. A few things I think you're off on:
I think you have Arizona and Kentucky too high - their records and play over the past month don't justify their higher RPI. I had them both as 8 seeds.
I think 3 of your 10 seeds - Vandy, UVa, and USC, are all too low. They all have enough really good wins and a sufficiently strong conference record to overcome lower RPIs. I had UVa as a 4, Vandy a 5, and SC a 6.
I don't think Oklahoma State is anywhere close to a bid. Their record in February is abysmal.
I had Ga Tech as one of my last 2 in, and FSU as one of the last two out. The big difference for me came down to Douglas being out and their record since he went out. Unless he gets back and they play well with him, I think that's really going to hurt FSU's chances.
