Oh and don't get me wrong. Whoever they hire Petrino included I will be rooting to be successful but if you want to talk about past fuckups being indicators of future performance you gotta be nervous as fuck about the possibility of BMFP.
That contract will be written tighter than a Chihuahua's asshole.
If I were writing it...
The strictest morals clause in the history of morals clauses. BMFP won't be able to fart in the general direction of anything female that is not his wife.
He won't have total and unconditional hiring authority - there will be at least one person that is not in the AD that will have to vett any hires he makes.
Any violations of employment law will be grounds for termination and probably some nasty penalties.
The carrot would be financial incentives for running a clean program( NCAA-wise as well as AUPD-wise), a decrease in off field player shenanigans, keeping his own personal house in order and out of the media, and winning some GOTDANG football games.
