Yeah I've also noticed that most of the people who don't win NXT don't show up, since Season 1. WWE planned to let a non-deserving person win NXT last season, because the plan was that most of the others would be brought up to the main roster anyway. And we haven't seen any of them.
They hired Kaitlyn when she was a model, without any wrestling experience, and now theyr'e training her. I think they did the same with Kelly Kelly. And we all know how long it took her to learn to wrestle, and get her own moveset. Imagine how long its going to take Kaitlyn. She has a divas title shot, when theres so many more deserving of it. To me, she is a joke to even have a match with Natalya.
