To be fair, she would get in anyway with or w/o TE. She just proved herself with the show, even if she was bad, she proved that she wanted it and took wrestling serious. The girls have the best shot at getting signed because well one is Miss USA, one was in FCW anyway, and one is Puerto Rican and has a Carlo Colon's endorsement. Divas also have a shorter window than men normally, so that helps them as well.
The guys really to me that have a shot are Luke, Jeremiah, Skids, Eric, Martin, and Andy for different reasons. I haven't seen enough of Tumbleweed to really judge him yet
The whole thing about TE is that they get a Raw or SD deal and immediate roster spot according to DeMott on MNM.
The others who get a FCW deal will just help move some tickets at FCW, so it makes sense to cash in on their 15 minutes of fame, just like they have done with the NXT guys and girls who went back there. You'll weed out who to stay and who to keep later, but you can make a quick buck off of them since they were on TV and a audience knows them, even if it is just at the developmental level.
