Frazier was miles out of Willard`s depth, Willard didn`t have Ali`s jab so wouldn`t be able to exploit his reach at all, Frazier would land hooks just like Dempsey did, his head movement and hands would be too fast for WEillard and he`d wreck his body with hooks to.
Frazier would work Willard over body head, the durable Willard may get past the 10th but Frazier stops Jess with a leaping left hook and a late rounds domination for a RSC or a count out- Jess had heart
Nah, Frazier robs his lunch money. Willard wasn't accurate enough to deal enough damage to a guy like Frazier, whereas Frazier was a quality operator who would certainly land on the defensively porous Willard. I don't rate Frazier as devastating a puncher as Dempsey, so Willard might see the end, but he would be a mess.
Frazier batters Willard over ten rounds and ends it definitively after that. His movement coming in would neutralize Willard's attack and his body hooks would take a terrible toll over the duration. I'll give Willard credit enough to tough it out longer than he should, but it'll be a one sided slaughter otherwise.
Willards size and durability would ensure a terrible beating over 12 to 15 rounds. Joe would put a career ending whipping on him
