I talked to a buddy of mine that is really good friends with Muschamps agent (who is definitely not Sexton by the way) and he said that Muschamp was talking with Texas even before the Peach Bowl. It sounds like to me Muschamp is tired of the "We are going to have a good defense as long as I am here. This is my defensive philosophy and I will hire someone that fits into it." talk that you sometimes hear from TT. That may be where some of this is coming from...
But then again, I am also convinced that TT was WAY closer to taking the Arkansas job than a lot of people out there so take it for what it's worth.
