if it wasn't for his last fight i would be saying kovalev would prolly beat him down...but kovalev has never been past 8 rounds and in that fight nearly lost...his last fight against that unknown cat went into the 7th and dude was gasping and bleeding even though he stopped him..made me go ...kovalev has power and youth on his side but what good is it if he can't fight 12 rounds...youre not going to beat bernard hopkins without no damn stamina...but bhop has to be careful...all the caginess and skill in the world doesn't mean you will beat father time.
