Worst stamina

[Primo Carnera]

Groves, Degale, Khan, Foreman, Bruno and the great "Ambling Alp" Primo Carnera!
Btw, isn't it a bit unfair to say Shavers? I remember him not only doing 15 rounds with Ali, but Ali goading him into making the pace and punching himself out. And in his next fight, he went the distance with Larry Holmes. Just cos he had loads of early KO's doesn't necessarily mean he had no stamina.

Well how the fuck does Foreman make your list? He only got stopped 1 time. Shavers is on there because he shot his wad several times for example Tex Cobb KO'd Shavers in 8 100% because Shavers punched himself out.
