I see David Otunga coming up and winning NXT tonight for several reasons. One Barrett is ready to be a star and doesn't need this push as bad as Otunga does. Otunga is extremely raw in the ring and needs a lot of work, so why not put him up there with some of the bigger stars to learn the ropes.
Second, I think Barrett will become an assistant for his current protege Chris Jericho, as Jericho is on a losing streak and that will get Barrett onto the main roster as well being a serious threat on the roster as well as continuing to work with Jericho, which are a great pair, both in the ring and on the mic.
