Even if he's mediocre, which he'll be at the very least, he'll still make more money in boxing than he ever made in mma. But I'm guessing that he's good enough even right now to be a legit HW contender. Same goes for Mark Hunt. These guys can hit hard enough to compete, and are both skilled enough at standup to make an immediate impact.

Right now I'd LOVE to see Hunt and Tua go at it.
