Where's the stretch? He was undefeated for more fights so he did surpass Floyd's unbeaten streak. That's not a stretch, that's a fact. And then when he was in his prime and past it he won real tough fights. He did have a long line of prime HOFer's he had to tangle with and beat many of them, and no one is saying that those losses weren't there, so how is that a stretch? He lost but fought so often that would invariably happen and he won so often and that is a testament to how good he was. He also fought more often and for longer, and given the meaning of longevity (long existence or service), SRR fits the bill. Floyd would be getting smacked around too if, at his present age, he was fighting a top notch, prime, in his 20's guy that was naturally much larger than him and he was fighting these guys on a regular basis.
