The Final Four is set, and Hoops and Howie break down the quartet that has advanced to college basketball's ultimate weekend: * An 11-seed (UCLA) that became the second team to reach the Final Four after starting its postseason in the First Four;* A 2-seed (Houston) that played an unprecedented four double-digit seeds to reach the national semifinals;* Two 1-seeds (Gonzaga and Baylor) who have been the top two teams in the country since this crazy season tipped off.Thanks, as always, to Dick Vitale, Chris McLernon, Ricky Sanders, and Sonic Librarian
