Absolutely nailed on its over. He can't take a punch, every opponent knows he can't take a punch, and most importantly of all, HE knows he can't take a punch. There is absolutely nowhere for him to go. Domestically AJ and Fury would both batter him. He's been totally starched by some Euro fighter and the Yanks will hardly buy him after Thompson knocked him out twice. Its over.
There is always the risk of writing a fellow off too soon. Price does have some nice qualities as a fighter after all, but I get the feeling this is pretty much it for him. I don't think that mentally he is the strongest/ most resilient guy around and he cannot take a punch. He will forever be walking something of a tightrope I feel. But, there is no reason (as said above) that he can't make some decent money still. I just don't fancy his chances at world level.
He could still be a contender for the British title he just needs to avoid being hit for the rest of his career. If he can manage that he'll be fine. Would love to see him in with Chisora though, that would be entertaining I'm sure.
