#3 Nia Jax
I'll be the first to admit I was a huge sceptic of Nia Jax when she first debuted in NXT. She just appeared as if she was not improving whatsoever while in Orlando. That's why I was very surprised to see her get drafted to the Raw roster.
However, she did indeed improve dramatically once she landed on the main roster. In fact, I'd go as far as to suggest Jax might very well be the most improved of all the NXT draft picks from last year's brand-split.
Jax might be the only women's star on the active WWE roster who is capable of doing well in an environment as chaotic as the Royal Rumble match. Her massive 6'0", 250-pound frame gives her the advantage she would need when it comes to possibly eliminating one of the male superstars.
Nia currently has other things on her mind, such as continuing her climb to the top of the Women's ladder. But, she could be the one called upon, if they decide to shake things up a bit.
