I fill out two brackets every year in my pool, and in one of them I took Belmont over Wisconsin in the first round.
What have you got?
Utah State over KSU.
Richmond over Vandy
Without looking at my bracket, I know I took Marquette over Xavier and I took Utah State over K-State. Utah State has the forth best record in this tourney.
Also, I picked it in one of my brackets, but I could see Purdue going down first round, only because they remind me of the 2001 Cyclones. Loose a game towards the end of the year on the road, a game you probably should have won. Than get embarrassed in the first game of conference tourney to a team with a lower seed, than get to the tourney and loose to a team you have never heard of before. I have a feeling Purdue is lacking a lot of confidence right now.
Also their sixth man Kelsey Barlow is suspended for the tournament. But they got a very good draw. I can't see them losing to St Peters or Georgetown/USC.
No real big upsets, although I do have Louisville in the Final.
Richmond over Vandy, Mizzou over Cincinnati, and Gonzaga over St. John's in Round 1, Xavier over Syracuse in Round 2, and Louisville over Kansas in the Sweet Sixteen. I'm not really sure if any of those would be classified as "earth-shattering" upsets - in fact, on a lot of those, the only reason why they'd be upsets is based on seed number.
