Right now, Bobby Petrino is as dangerous as a ring of electrorefined Plutonium-239 in the hands of Al Qaeda.
It may take a while for the toxicity of what he did at Arkansas to fade, and it may not ever.
At this point, the best thing he can do is go on any ESPN, CBSSports or NBCSports show that will have him and talk about how sorry his is and how his life has changed.
It wasn't the affair he was having. It was the breach of protocol (and likely federal/state law) he committed in hiring his mistress, then lying to his bosses about everything until he had no choice but to fess up.
No employer wants to touch someone like that, barely nine months after it all went down. It will take a desperate program in dire straits to go there. I will be shocked if anyone puts him on the sideline for the 2013 season.
That's why I laughed my butt off at all of the boogs who thought they would get him. Even Jay Jacobs isn't that stupid or desperate.
