I thought it was pretty obvious Sark would leave for USC if he ever got the opportunity, he was merely waiting for the Reggie Bush noise and NCAA penalties to be forgotten and die down.
Sark is a natural liar - it's in his twitchy eyes. I can tell that he practices his talking points before he gives press conferences - when he says his smart talking point, it's the only time he makes eye contact with the audience - practiced. When he's forced to think, his eye movements are so bad. He's overwhelmed as a HC. I can guarantee he's going to fuck up at SC. He's not bright enough to handle all the HC shit.
