I'm no expert, just havin' fun. I have a boring bracket up until the Sweet Sixteen: the 1-4 seeds in every region, except #5 Tennessee. Then the whole bracket goes loopy, with Ohio State my only #1 seed going to the Final Four. And the strange thing is, I think Ohio State may be the weakest of the #1 seeds. Their bracket, however, does them big favors. Only the A&M/Memphis winner should be tough for them.
I have two #12's beating #5's this year: Old Dominion and Illinois - the latter sort of a non-rational guess. My other early upsets are VCU over Duke, Winthrop over Notre Dame,George Washington over Vanderbilt.
Final Four: Oregon (winces), UCLA, Georgetown, Ohio State. Texas is my emotional favorite.
