Ofc nobody beats prime 204 lbs Frazier on the inside. A 230 lbs guy could simply lean on him like Ali did in the second fight.
Perez let Ali pull the back of his head down all night long which is illegal genius but I'm sure you must have already known that right???
It’s possible. Both these men were more or less infighters with one of them being significantly larger than the other. Both possessed great power but Bowe was possibly more durable.
