#3 Paige VanZant
Where to begin with Paige VanZant? The 24-year-old has had her ups and downs in the Octagon since making her debut back in 2014, putting together a record of 4-3-0 in that time. Though "12-gauge" Paige has struggled for consistency, it doesn't seem to have affected her star power at any stage.
The confident, charismatic Oregon native increased her popularity with a successful stint on Dancing With The Stars back in 2016, ultimately finishing the season as runner-up - quite an impressive feat for an, at the time, little known mixed martial artist.

VanZant has the looks, charisma and fan base to make the transition over to WWE should she decide to do so. She is currently plotting her comeback from a serious arm injury sustained during her last Octagon appearance, against Jessica-Rose Clark in January of this year. While it certainly appears she is driven to get her MMA career back on track, she has previously spoken of her admiration for Ronda Rousey and explained that she wanted to emulate the success she found as a pioneer for women's MMA.
Would it be a shock if that ambition carried over to PVZ pursuing a career in WWE? I don't think it would.
