It was bad news to try and overpower The Tiger as Hurricane Carter and Florentino Fernandez found out. Tiger would have savaged the tough guy's body and stopped him in 8 or 9, sliced him to ribbons.
Barkley was a pretty rudimentary fighter, when you get right down to it. I would reckon a guy who was dominant at 160 and who could hack it at 175 would be way too much for him.
