I will not have Smith clinching and holding for dear life in every mythical matchup we put him in but i believe this is what he will have to do against Tua in order to, atleast, survive and go the distance with him. Smith has REAL power but i think Tua would shake it off with the help of his legendary chin. And david was also a tad more durable. Tua by a close decision or late TKO.
I think bonecrusher shocks the world and KOs Tua (out cold, they need smelling salts and a neck brace and the whole 9) in 4
Two of the most overrated boxers on the forum. Tua should logically get the benefit of the doubt with his superior hand speed, technique, ability, and work rate. I'd say Tua by decision.
