Look, he instantly moved on from BYU. It was his right to do it, but we can do the same. We don't owe him anything.
And, because of his new gig, he's trying to gut our program by dragging coaches and players away. Again, that's his right, but it's our right to see him as the enemy (in a sporting sense). That's where we are. That's the way he wanted it. All he had to do was make the usual "grateful for the support" communication and he would have remained well thought of by the vast majority of us even as he's working to gut the program. But he didn't, and so many of us feel no obligation to wish him or his new program well - they are competitors.
