#3 Daniel Bryan
It seems that Daniel Bryan has possibly turned babyface again, after a year of being a heel, where he held the WWE Championship. Bryan could be in the last few years in the company, as he turns 39 next May.
Bryan, at the height of his popularity, was possibly one of the biggest babyfaces in the history of the business. We could perhaps see him have yet another babyface run and bring back the "Yes! Movement" in WWE.
Bryan speaks eloquently and passionately about a lot of things, and his "Earth Warrior" heel gimmick from earlier this year was a reflection of his real-life persona. To be "The Guy" of WWE, being a locker room leader as well as one who stands strongly for his/her beliefs is important. Bryan certainly ticks those boxes, while his in-ring prowess is perhaps unmatched as well.
He could be the face of the company for the next year or two, have yet another memorable heel run before he hangs up his wrestling boots for good.
