I don't think there is any way that Thug U will dig deep enough to pay Charlie's buyout. Now Texas might offer a Walmart "blue light discount" that could make it happen. But if that did happened, wouldn't the Canes feel like they were buying damaged goods?
Just thinking out loud here...
My understanding from an article I read is that, while all of his contract is guaranteed to him ($19M?) if he is fired, if he leaves, there is no buyout. (I wonder if Sexton is his agent...)
