We had Hogan in the 80s, Austin in the late 90s, the Rock in the 90s/00s, and to a lesser extent John Cena in the 00s/10s. Wrestling needs a new breakout star to capture mainstream attention. Who has the most potential to do it?
There is literally no one right now who can escape the soul-crushing WWE branding machine and go mainstream. That's the entire point of their system now. The brand is bigger than any star by design.
