If he leaves for a better offer, he leaves. He's got a lot going for him here. The AD appears to love him, the board appears to love him. He's basically got free reign here at this point (like Patterson at TCU). He won't have that anywhere else. SL knows that. And it comes back to that age old question of whether that redshirt sophomore should enter the draft. Could they mature a couple more seasons where they are and get the experience they need to survive at the next level or could they make the jump and hope they can swim. I wouldn't dare blame SL for taking a better offer. This is a game and he should be paid on his performance. I want to hold onto him, and I hope he sees the advantages of staying here, but if he leaves for an offer (and he will get at least a few this season), then he leaves. Unless we all want to chip in thousands of dollars into the "keep SL here" fund, it's out of the fans, and to an extent, the university's hands.
One observation I will make is that looking at his past stops, he didn't have much personal connection to location. He seems to have a personal tie here with the northern Texas region and Oklahoma. Unless Tech offers him, which they very well might, I think there's a good chance he stays.
Side note, Brett should take this story down. It is speculative trash. Lots of research about past coaches and players but very little into SL.
