Who's your Final Four

On Monday I finished my annual exercise in futility — picking the winners of the NCAA men's basketball tournament. I already have 2 wrong — I picked Alabama-Birmingham and Arkansas-Little Rock to win First Four games and, of course, both lost. My Final Four are Ohio State, Texas, Kansas (which will please my editor) and Wisconsin. I have Ohio State beating Texas in one national semifinal, Kansas beating Wisconsin in the other, and the Buckeyes and Jared Sullinger beating Kansas (much to my editor's chagrin) to win the whole enchilada. Who are your Final Four teams and your national champion?
