Tarver had stamina issues anyway. Now, at 37, hes gotta come back down from ballooning up for that Rocky film?? If he does ever make it back down hes not gonna have that much in him, calzaghe's ferocious workrate should make this an easy win for him. Personally I dont see Tarver ever fighting at light heavy again after Hopkins, I wouldnt be surprised if he missed weight for the Hopkins fight. 37 is pretty old to take off all the wieght and still be in fighting shape.
