Higher paycheck. Can't say that I blame him. I probably would do the same thing if I didn't have ties to BYU. In Broncos last year Utah tried to hire him but BYU counter offered twice and Atuaia, Bronco, and Anae were able to convince him to stay at BYU. Sitake was interested in keeping him but BYU wasn't willing to put up the money needed to keep him.
