I think he meant what happens to Chavis at LSU if Miles leaves/gets fired. That's the biggest issue. After a dissapointing '08 D and a progressive '09 D, the '10 D has become lights out. I don't want to see what a new DC would do after these guys have gone.
I am hoping that this is Miles being Miles, that like way he made the coaching changes after the Malveto debacle, allowing them to save face, he is being compassionate towards jefferson and will make the change but in his own way.
