As I suspected, it looks like Buzz is going to be staying at Marquette. I don't know why he would leave his situation there, he's got great support.
From Jeff Goodman at FOX Sports:
Buzz Williams is likely remaining at Marquette, sources have told FOXSports.com, and could ink a new deal with the school prior to the Final Four next weekend.
Williams, 38, who has led the Golden Eagles to three consecutive NCAA tournament appearances since taking over after Tom Crean left, is on the verge of signing a new contract that will pay him in excess of $2 million per year.
Is it finalized? No. However, it certainly looks like OU is going to have to start moving down the list.
