The Big 12 takes on a new look in men's basketball next season, and not just because Nebraska and Colorado are leaving.

Four teams will have new head coaches. Underclassman declarations for the NBA draft will cost Texas and Kansas three players apiece.

The coaching shake-up is the most significant in the conference since 2006, when six schools had first-year coaches. Only the Atlantic Coast Conference has had as many coaching changes this year.

Texas loses Jordan Hamilton, Tristan Thompson and Cory Joseph to NBA draft declarations. Kansas loses Marcus and Markieff Morris along with young standout Josh Selby.

Jayhawks coach Bill Self said Baylor and Texas A&M, which is looking for a new coach, should be the preseason favorites.
