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

[Dark Lord Al]

I think leonard was better then hearns and duran and think out of the 3 he be the hardest for PBf.

I also think Leonard was the best of the lot....And would beat PBF at welter.

I think they all beat him , i mean come on hes not fooking superman lol
