Tomorrow’s men’s basketball regular-season finale will decide the last conference titles

The GIST: The regular season wraps up tomorrow, and while some squads have already secured conference titles, others are still fighting for their crowns — and top seeding in next week’s conference tourneys.

The done deals: Four early birds clinched sole ownership of their season titles this week: No. 2 UConn in the Big East on Sunday, No. 3 Purdue in the Big Ten on Tuesday, No. 4 Tennessee in the SEC on Wednesday, and No. 5 Arizona in the Pac-12 last night. All are likely March Madness No. 1–seeds — if they can keep their sh!t together until St. Patrick’s Day, aka Selection Sunday.

The tight races: In the Big 12, No. 1 Houston holds a razor-thin lead over No. 6 Iowa State, and they must win tomorrow’s game to guarantee sole ownership. The catch? They’re playing No. 14 Kansas, a fierce blue blood and one of only three teams to crack the code and defeat Houston’s elite offense this season. Gulp.

• The most exciting weekend matchup? The ACC title battle between No. 7 UNC and No. 9 Duke. Duke trails UNC by one game, but if they beat their blood rival tomorrow at 6:30 p.m. ET on ESPN, they’ll force a tie for the conference crown. College hoops at its absolute best.
