Was Shavers stamina that bad? He went 15 rounds with Ali, and the distance once with Holmes, and KO'd Roy Williams in 10. Shavers stamina cost him in the Tex Cobb fight, but he was pretty much past his best by then. Cobb was a human anvil type. He could tire you out when you hit him.
In terms of gassing, Foreman might have gassed sooner than Shavers did in the 1970's.
