Agreed Chazz has some abilities, and sometimes it takes a loss or two to realise the sacrifices you have to make to really make it in this sport.
For example - Don't slate me for harping on about Yusaf Mack, but it is a similar example, he was a badly prepared, didn't train hard enough weight drained Super Middleweight he lost a couple of fights because of this, believe it or not he is a talented guy but had spent much of his career slacking off relying on his natural ability and the guys around him telling him he was the best. Yes I came in and made changes, yes i told him if he wanted to be the best he had a lot of work ahead of him etc, but he had to want to make the sacrifices, a trainer can't give a fighter desire, those loses made Yusaf take a long look at himself and now he is one of the most dedicated guys around, you have to keep an eye on him over training now. He does what he is asked to do and pushes himself, I didn't know him before the losses, but I can't imagine he would have had the same dedication before. He will never lose a fight again being badly prepared or unfit, if he loses he will lose because the guy opposite him is a better fighter.
Maybe Chazz will be in the same boat, he has been carried to a decent record and in his first step up in class he fell well short. hopefully if he really has the desire to make it in the sport he will make changes and dedicate himself the way he needs to if he is going to more than a nearly man. He needs to be told some home truths and work hard then work his way back, I think the same will happen to Arreola as well to be honest in time.
