To be fair, that's not a bad boxing display from him and his jab was nice and quick. Still, there's nothing there that leads me to think that Tua wouldn't be able to close him down and force his own brand of slugging into the fight.
He probably could lay it on early, but I wouldn't bet on him doing it for too long after that. Tua was a very one dimensional fighter, and most men he couldn't knock out immediately gave him tough matches heading toward the 12th. After his loss to Ibeabuchi, he only won by decision five times, against generally inumpressive competitors, and in two cases where it was contested either by way of majority or split decisions.
Such a shame that Diaz's prime was cut short by a 41 year old Oliver McCall- Truly the scourge of heavyweight boxing.
