Could Prime Gene Fullmer beat the whole fab 4?

Really Duran and Hearns? I feel they’re perfect “victims” to his rough Billy Goat style of “boxing” he was a very cagey guy with his defence too, had quick feet and wasted no time getting in (I was shocked by this watching Robinson v Fullmer 1) he’d definitely be able to muscle either guy if it became a inside war for my 0.2 he was strong, creative and very wilful, I think that old school way of wrestling someone around to drain there legs / wind would do work on Hearns and the 160lbs Duran. Didn’t Leonard also avoid having to fight Iran for his physical way of fighting?
