My opinion has nothing to do with his show-cause penalty. It has everything to do with the NCAA's selective enforcement/punishment. His show-cause is up in 8/2014, but if you think the NCAA is going to simply "be okay" with Tennessee rehiring Pearl, then your head is buried in the sand. While it's true, they can't stop it from happening, they won't be doing Tennessee any favors before the Infractions Committee if Pearl slips up under the watch of the Tennessee AD. They will nail us to the wall, and the idea of rehiring Pearl has to be weighed against that possibility.
The original point being, the Petrino and Pearl situations are almost nothing alike, and the idea that UL rehiring Petrino is justification for Tennessee rehiring Pearl is just misinformed.
