Wasn't it McMichael who "blew up" on the sidelines last year when the offense was playing poorly?
Personally, I believe a leader should be in a "leader" position. Granted, it speaks NOTHING of the personality of the person in the position... everyone is different. But, firmly believe the QB should be the leader.
That said, I think AJ needs to take over. If the guys in the huddle look to one player for the play call and another for motivation, it can be counterproductive. I'm not saying it CAN'T work that way. Just saying it's better for the QB to the voice of the offensive team.
I honestly believe AJ could mature into that role. He's a fighter and let's face it, the kid never gave up on the team no matter what happened. However, he does need to be a vocal leader. "Lead by example" only gets you so far with a bunch of overpaid egos. Eventually, you have to command their respect with vocal leadership.
If AJ can mature into the vocal offensive leader of the offense, I think the rest of the "fears" about him can be disspelled. Winning changes everything.
