So, for everyone's edification, IF Nebraska is indeed attempting to hire Rhule... Carolina has offsetting language in their contract with Rhule that if he were to take another job... they'd be able to recoup 'most if not all' of the $40 million they owe him.
Ergo, it is likely that Nebraska and Carolina have been trying to work out some kind of compensation deal between themselves. It's basically a discussion of how much debt Nebraska is going to take on. Rhule is NOT worth $10 million/year, so Nebraska is unlikely to pay that, however Carolina would certainly like to offload as much debt as they're able. So, what would hypothetically happen is Nebraska signs Rhule to let's say five years at $40 million ($8 million/year) and then Carolina would pay $2 million/year for four years until they're paid off. In the end, Rhule would be making $10 million a year for four years but from split sources. (Again, this is hypothetical. No need to nitpick the actual numbers).
I can tell you what's NOT going to happen is Nebraska signing Rhule to some $20-$30 million dollar deal while Carolina continues to pay $40 million. That's not happening and it would violate the contract language allegedly in place with Carolina.
