I think, since Hopkins is 43, fighting young prospects and establishing his dominance among them will several fights, much time, and earn him relatively little money. I think he wants to end with a legacy enhancing fight, avenging the loss to RJJ, and make a lot of money on the hype that will likely surround this fight. I can't say I'm dissapointed, the man deserves it.
He would have very little chance against either Adamek or Dawson. Froch would have been agood fight a t a weight where he hadn't held a title before and would have been an undefeated scalp on Bernard's belt. But, assuming Roy gets pat the Aussie, RJJ v BHop is the biggest and best fight Bernard could get at this time. Unfinished business and all that. Very much looking forward to this one.
