Pryor's real limit was 10 stone and I think the guys mentioned above, Honeygan/Curry/Starling would all have been too much for him. Now Ray would have beat those guys too I say. Ray was top 3 ever at the weight. Aaron just not natural or big enough to cause Ray trouble. The single most important element in boxing is to get your opponents respect and Aarons lack of a real punch moving up mean Leonard will never fear a mix up, can't be outreached, can't be outsped and definitely cannot be outboxed..
Oh and can't be KO'd
