#2 AJ Styles

Speaking of accomplishing everything there is to in WWE, AJ Styles is another perfect example of that!
Not only is that evident by his WrestleMania dream match with Shinsuke Nakamura, but also by his multiple title runs and the time he has spent as the company's top guy as well.
If nothing else, Styles has succeeded in proving all the naysayers wrong and has absolutely no reason to stay in WWE anymore!
Beyond that, there are a lot of opportunities for dream matches outside of the company, which is another great reason why Styles should jump ship to another company!
In the end, Styles, especially after his WWE run, is the kind of superstar that can take a company to the top of the mountain.
With that being said and nothing else to prove back in the land of WWE, why not test the waters, go back on the indy scene and maybe even help another company surpass the sports entertainment giant?
