Who Will Be the No. 1 Seeds?
Things got a little more complicated at the top on Friday night when Duke beat North Carolina in the ACC tournament semifinals.
Prior to that game, the Tar Heels were likely going to be a No. 1 seed. They still could be, but it's less of a sure thing.
Duke, however, put itself in the conversation for a No. 1 seed. The Blue Devils are a much better team with Zion Williamson on the court, as they've proved since he returned from a knee sprain that caused him to miss the final five games of the regular season.
Williamson had 31 points and 11 rebounds in Duke's win over North Carolina. The Blue Devils had lost their previous two games against the Tar Heels this season—one without Williamson and one in which he left early due to injury.
Duke should be a No. 1 seed now, and it will solidify its case if it beats Florida State in the ACC tournament championship game on Saturday.
In Friday's other ACC tourney semifinal, No. 1 seed Virginia was upset by Florida State. However, the Cavaliers have only lost three games this season, including two to Duke, so their resume should still be strong enough to earn a top seed.
Gonzaga is in the same position as Virginia. The Bulldogs have only lost three games this season, but they fell in the West Coast Conference tournament championship game to Saint Mary's. However, they should also still earn a No. 1 seed.
With Duke, Virginia and Gonzaga seemingly locked in, that leaves only one more spot. North Carolina and Kentucky are the top contenders for the last No. 1 seed.
