4 WWE superstars whose careers have peaked and 4 whose haven't

Has peaked: AJ Styles

The champ runs the camp for now

AJ Styles has now held the WWE Championship for over 300 days. His reign has unfortunately felt like an afterthought at times, but it's a tremendous sign of the confidence that the company has in him to let him run with the title for so long.

At 41 years old, it's unlikely that Styles will get another run like this once he drops the championship. He's had a long career, and arguably his first run with the WWE Championship was his peak. Styles will remain a major player for as long as he wants and is able to, but he'll probably never scale a height as high as this once he's off it.
