Same. I think he has the style to pepper Tua from range and the chin to withstand any huge leaping LH bombs Tua might land.
To be fair, if anyone can turn a fight around with just one punch it's Tua. But yeah, I don't think he gets the KO here.
I'm not sure how Tua finds Parker to be honest. Parker is a legitimately skilled boxer who moves well. Tua isn't. Tua has the power to KO anybody but he's really limited. I think Parker works him out easily enough and gets a decision in a pretty boring fight.
