No. Morrison was an admitted juicer and carried less flab than Whyte. Whytes body fat tends to make him slightly top heavy and disturbs his balance when he wings the left hook. Granted that is all I believe Morrison has over Whyte.
I noticed Morrison almost always lands the blow by making some small forward momentum with his legs, Whyte instead almost always from a standstill. Perhaps this is the main difference that makes Morrison's left hook at least more powerful.
Always thought Morrison's hook was overrated. Who did he ever knock out with it, really? Then again, white has four knockouts in his last ten fights, so his power may not be as sold, either.
I'd say that Wlad had a better left hook than either. Better jab and right hand too, which creates more openings for the left hook.
Tommy threw it with better technique (that explosive coil) and a better delivery system (working his way in with good judgement of distance). Whyte possesses a heavy hand, but he's infinitely more reliant on a guy walking into it with his right glove anywhere but where it should be.
Morrison's left hook was aesthetically more pleasing and also had very good form. Whyte's probably has more power behind him (he is naturally bigger) but you can avoid it too. Morrison was more trigger happy with his left hook and also landed it more frequently. It was overall a more "natural" weapon.
Morrison's was better. It was all he had, so really, it had to be better. Not that I particularly enjoyed watching Whyte's overhand right spam against Povetkin, but I assume there was method in it somewhere.
Morrison's was more pleasing to the eye and probably delivered with more raw power. But Whyte's is often thrown as a sneaky counter so it's probably more dangerous as he's more likely the land it on an opponent who walks into it and doesn't see it coming.
