If he didn't believe he had a shot to win this year, then he has a larger sense of entitlement than I imagined possible, and his lack of belief in his players should be quite disturbing to any future recruits. Although, at LSU, he is clearly expecting mercenaries not recruits.
Demanding his assistants leave with him is pompous as hell. As far as Charlie Weis, Jr goes, I don't know much about him other than who his Dad was. So, do we have a case of another spoiled, entitled coach's son in the making? If so, then emulating Lane as his apprentice seems to be the perfect fit, and there was no reason to explore options outside Kiffin's slime trail.
