I agree with you that if Miami keeps Diaz, they probably win more games this year.
But that’s kinda like when you break up with someone that you really need to break up with. The period right after that you usually feel worse than you did when you were with them, but long term it’s for the best because you were never going to get out of it what you needed.
And I disagree with your view that a burn down has to mean you take the players and change them. As I said previously, that’s why coaches frequently have Year 0s and go young with their recruits and you see large amounts of transfers. They aren’t even trying to change the old players.
I have no idea if Cristobal is going to be successful. I’d make the same argument with him that I did with Mack Brown: you have to wait until a recruiting CEO has three classes of his players on the roster, before you can judge.
