Yes he got beat by one of the at the time top 5 HWs and beat him inbthe rematch. Bruno couldn't box on the back foot at all. Look at Rivas fight were Whyte is jabbing Rivas head off in most rounds as well mixing it up going to the body effectively. Whyte was clearly the more well rounded boxer of the two.
Big Frank would flatten Pudding Whyte early - it would be painful to watch for the public and far too much to take for @Aydamn Glass all over canvas and shreds may even hit tier 2 spectators.
I vote Bruno because he would smash Whyte to pieces - would say the same if he was with Senior Wardeen
Watch what a difficult fight Bruno gave Lewis and then say Whyte has a chance. Bruno is near AJ level (not quite elite but not far off). A level above Whyte. Bruno is underrated imho. Very good punch variety, excellent jab, strong, powerful and good ring iq. He only lost to 2 ATGs, s very good fighter in Witherspoon and a very good fighter in Bonecrusher that he really should have won. Bruno would ko Whyte mid rounds.
