It was a good comeback by Haye, he has serious power.

I think the main reason he wants to stay at heavy is the stamina issue, he won't have to work as much as he did last night.

As for his chin, I think it's a defence issue rather than out right bad chin, he's also shown in his last two fights at cruiser that he has a good heart. Be a real shame if we never see him against Enzo.
