I have to think that the ACC and anyone with a moral compass who supported Louisville's invitation to the ACC realized it was a horrific mistake. Even if one only cares about football or some other narrow focus must realize that their football program is obviously suspect.
Although Louisville deserves to go back to Conference USA or demoted to G5, they will not be expelled by the ACC, even if they rightfully regret inviting Louisville.
As for NCAA penalties, I don't think they receive the death penalty they deserve. They have not quite reached the same level of reckless disregard that SMU had, but they are close. If they somehow breach their current level of stupidity and pull this or some other stunt again, they will receive the death penalty. At they very least, they need to have their MBB NC vacated, ineligible for post season play for at least 3 years, and show-cause penalties for Pitino for at least ten years, and Jurich for a numbers of years pending investigations of his shady activities.
