I don't think Andy really thought he was gonna win. I'm sure he wanted to, but I don't think he's delusional. He can't say that publicly because that doesn't sell fights, but that Salt guy seems like an actual fighter, and I think Andy didn't want to bitch out like Ralph did win or lose.
I don't think Andy thought he'd get his bell rung either, but I can't criticize him too much. He got paid, he got to go to England, he got to meet a bunch of people like Sam Hyde.
Even if he lost the fight, it still seems like a win for him.
