That's what the Statesman's Kirk Bohls is saying.
According to Bohls, a source 'close to the Longhorn coaching staff' told him that Davis has been unofficially contacted by SMU about their vacant head coaching position. And by 'source' he means Bill Little.
Davis has been with Mack Brown for 12 years now so it's doubtful that he's leaving for another coaching job at this point in his career. But if he did leave, a source close to Barking Carnival told me that the leading candidates to replace him would be Lynn Amedee, Major Applewhite and Watson Brown.
