Overall No. 1 Louisville is a slight betting favorite to win the NCAA tournament, but Las Vegas casinos think any one of several teams have a legitimate shot at winning college basketball's national championship.

Executive Director Jay Kornegay of the race and sports book at the Las Vegas Hotel & Casino had Louisville at 9-2 odds on Sunday night after the tournament's seedings were announced. Right behind the Cardinals were third overall No. 1 seed Indiana at 7-1, and Duke, a No. 2 seed, and Florida, a No. 3 seed. at 8-1.

Jay Rood, vice president of race and sports for MGM Resorts International, said Louisville would also be the top favorite at its 10 casinos on the Las Vegas Strip.

But Rood said he thinks opinions of the top 16 teams in the tournament will vary widely.
