Yes Haye also noticed the chin problem. Haye likes fighting guys with suspect chins. Enzo, Audley, and even Ruiz could be called suspect chins.
Cos last time he fought a hard chin guy, well i dont if its the last tough chinned guy he fought, Carl the truth thompson. Haye threw the kitchen sink at Carl, but Carl was still eager to land his own on Haye to test his chin out as well. Haye didnt like that. He was thinking "hey, you should be on the floor now"
Haye would have liked the ref to stop Carl Thompson from taking more punishment but Carl made the ref feel that he wasnt ready to be stopped.
