Xavier and Indiana had chances to give their NCAA Tournament resumes a significant boost. But the Musketeers lost 89-87 to No. 25 Marquette, and Indiana fell 72-59 to No. 23 Oregon. Those aren’t bad losses by any means, but they were squandered chances. And Xavier and Indiana are very much on the bubble. Texas and North Carolina are two bubble teams whose outlooks seemed pretty precarious a couple days ago. Now they’re still alive in their conference tournaments. The Longhorns snagged a huge win over No. 14 Texas A&M, 94-89 in double overtime. The Tar Heels beat Wake Forest 68-59.
