Or it could be more innocent, as in Belichick has a blind spot when it comes to his son's coaching abilities. It really doesn't have to be a grift. It could just be BB trying his best but being out of his league. Or BB thinking he's trying his best, but really he's an old man who lost his spark and hasn't admitted it to himself yet. It could be an impressive long game sabotage effort by Wuffies, who created a thing called "Jordon" specifically to cripple UNC's football program. Well, admittedly, this last one is unlikely. But the point is, you can say that this is an absolute disaster without assuming it's "lining their own pockets."
This is, I think, what identifies you as a former GOPer. The GOP's mentality is always to personalize the conflict. Bad things happen because evil people do them, and the proof that they are evil is them doing bad things. Hence we get all the bullshit about how Obama and the Dems are trying to destroy the country; it must always be personalized, and the harm must always be intentional.
In the last few years, liberals have adopted this approach -- but only because Trump etc. have made it an inescapable conclusion. Otherwise, I think we tend to be more forgiving, more aware of human fallibility. Sometimes, mistakes are just mistakes. That's not to say that I think BB definitely is not grifting; I have no idea. I just don't see any reason to jump on the intentionality train.
I suppose I should speak for myself more than others. I am acutely aware that people fuck up all the time. When someone fucks up, I don't tend to assume it's malicious. Only if I have evidence that it's the case. There is an admittedly unfortunate habit in the language to use the language of intentionality to describe mere argument. It's an old abstraction. For instance: you're trying to have your cake and eat it too. That uses what appears to be the language of intentionality, but the "trying" part is actually just a description of debate.
