5. Big E Langston
Big E is one of the more underrated talents in WWE right now. With his imposing physique, unbelievable quickness, and tremendous endurance he's already got the physical tools to be a dominant player. But, Big E isn't just another muscle-bound guy. He has a ton of charisma and can resonate with the crowd on a level many superstars yearn to achieve.
Big E has already faced off against the Elite, sort of. He was part of a video game contest between the New Day and the Elite on their podcast. Given that he respects them, and they respect him, it may not be that far fetched to see Big E jump ship.
Chances of him joining All Elite Wrestling: 50-50. His current WWE contract would have to expire first, and then there's a good chance the WWE will make him a major offer just to keep him out of the clutches of the competition. Big E is a man who should be a lot higher on the ladder, challenging for the big belt on Raw or Smackdown. If WWE insists on keeping him in a tag team division, he might be tempted to join AEW.
