NCAA Tournament Bracket Has Half of Final Four Set After UConn, Butler Pull Off Thrilling Wins

Thanks to a couple of late, dramatic wins on Sunday night, we now know half of the Final Four — two teams that not many people would have predicted to be here once the season began.

Butler returned to the Final Four just one year after making a Cinderella run all the way to the national championship. This year's repeat Final Four performance may be even more impressive, though, as the Bulldogs were an 8-seed heading into this year's dance, while last year they were a No. 5.

UConn started the season unranked before shooting up the rankings early on, falling back some during the middle of the season and now riding a hot streak that includes five wins in five nights during the Big East tournament before racking up four wins in the tournament to get to the national semifinals.
