If PBF fought in the era Leonard, Hearns and Duran how do you think he do

I might give him some credit if i didn't fall asleep during his fights.

Snort some lines of coke or crystal meth.

That would indeed fix the problem. I think he'd be a big factor (like frazier in the ali era) but he wouldn't be the clear cut dominator of that era.
