Hearns would have no shot in Hell at 175 against a Charles, Spinks, Foster, Moore, but could he beat a Conteh-level light heavyweight?
I don't think Conteh can outbox Hearns (who could??)... I think he either gets decisively outboxed, or finds a way to pull it out late like SRL did.
Conteh could rough and mean, he could fight on the inside, and he had power in his left hook. Its possible he could draw Hearns into a fight and stop him.
