This person is allowed to be hired by anyone, the show-cause penalty has expired, this is simply his attempt at clearing his name. He lost a defamation of character suit in LA courts and is grasping at straws. His lack of employment in the field of football is a direct result from his actions for being a bag man and taking the fall for Pete Carroll. That sounds like a "him" problem.
I'm not talking about this case in particular, just the concept in general. Every school should be allowed to make it's own hiring decisions. The NCAA putting the "scarlet letter" on certain coaches seems ridiculous. You should be allowed to hire anyone you so choose.
Every school is 100% free to hire who they want, they are also free to join or leave the NCAA, no one is making any school do either. I suspect if the employee was desirable enough and valuable enough a school would make that choice. Thing is, up in till now, no one has found the employee who is that perfect.
Very rare indeed.
Chip Kelly was given a show-cause penalty after he already left Oregon for the NFL and it has since expired, but UCLA did hire him. He is the first Division I coach to receive a job after the show-cause.
And different sport but...
Kent State kept Rob Senderhoff on the basketball staff as an assistant and later given the head job after he was given a show cause penalty due to his time under Kelvin Sampson at Indiana. Sampson ended up returning to college at Houston after his expired.
Bruce Pearl was hired at Auburn after the penalty was up, the first ever for a power conference member.
