Re: Why wasn't AJ on Raw???
AJ is more of a case of booking than anything else. AJ has been booked for most of her run as more like a underdog Face, who spends most of the match getting beaten up and thus isn't able to show off her skills whereas in FCW/NXT she was booked more evenly and was able to show off her ability and skills. If she's able to wrestle unrestricted AJ probably is ranked up there alongside Natalya and Naomi as the best Diva wrestlers on the main roster.
I see. I have never seen NXT, so I'm restricted to just what I observe in the WWE. I'll take your word for it.
