You've just compared an old SSM who wasn't at his ideal weight against THE hardest punching LMW of all time and one of the hardest punchers EVER? Wow!
Not comparing them, Im just saying it was a hell of a punch that he took. Not too many other examples of Floyd eating a clean hard shot.
There is no way to pick Jackson here unless you're betting him as a large underdog. Truthfully, I think he'd lose to Canelo too.
Terry Norris went about 5:50 minutes before eating the first clean shot. And it was more than he could handle. Could Mayweather go 36 minutes without eating a single flush shot?
A 40 year old Mayweather..most likely not. A prime Mayweather...quite possible. Norris' defense I don't think is comparable to Floyd's.
