UCLA’s odds to win the national championship understandably improved during its undefeated run through February. So did North Carolina’s.

As of today, The Bruins and Tar Heels are co-favorites to win the NCAA tournament with 6/1 odds, according to Bovada. Both teams had 9/1 odds on Feb. 1, which slotted them behind only Gonzaga at 15/2 and Kansas at 8/1.

Arizona, whose only loss in February came five days ago when UCLA snapped its 21-game winning streak at McKale Center, was 10/1 Feb. 1 and is now 16/1. Oregon rose from 28/1 on Feb. 1 as high as 10/1 Feb. 13 despite an 82-79 loss at UCLA Feb. 9. The Ducks are currently tied with Louisville for the eighth best odds to win the national title.
