Before I go on let me just say I am a fan of Paige and believe she has a bright future...
Now where was I? Oh that's right! NO!
First a foremost WWE have had a policy for a while now that they won't debut anyone under 21 on the main roster, Paige is not 21 yet.
Secondly, if you watch her on Nxt most aspects of her 'performance' still need work. She doesn't sound confident on the mic, she doesn't have a natural flow and sometimes gets caught in awkward moments along the lines of, "I'm a figh'er and I'm here to figh' and if Summer Rae wants to run her mouth then I'll figh' her and shut her mouth for her." Also, she doesn't seem at ease at any time except between the bells. If you watch her entrance and compare it to Summer Rae, Emma or any of the main roster Divas she seems to phone in the poses on the apron and the movements around the ring.
In matches she's great, every bit deserving of the first Nxt Women's title, but she needs more time to grow into a WWE calibre performer in all aspects but her ring work.
