Novak won't win, but he will make it onto the Smackdown roster. Wouldn't be surprised if there was another love triangle, with Novak taking Kaitlyn's place.
But Byron Saxton and Brodus Clay look to be the best. I would even say they have the best chance of becoming WWE champion (or at least World champion), in a few years. Bateman is a pretty good choice too, because he's hilarious in his own way.
Johnny Curtis just looks lame. But they might be making him look that way on purpose.
And I think Connor O'Brien has a good shot of making it on the roster. He's good at working his rat-guy heel gimmick, and he's solid in the ring. At the very least, he could be a solid jobber.
