#6 Chad Gable
Proving that he can truly hang, Chad Gable had a string of phenomenal singles matches at the tail end of his Smackdown run alongside the likes of AJ Styles. It's proof that despite his diminutive stature and management's lack of real faith in him, Gable could be what Jason Jordan couldn't for management.
The same issue currently plagues Seth Rollins, despite being a favoured Top Superstar allowed to flourish with the top RAW championship that is still there (Where's Brock after all?). Rollins is unable and disallowed to step out of the shadows of Roman Reigns, even though he is far more popular among fans.

It's funny though both Chad and Seth also share Jason Jordan in common. However, none of that matters as both men could put on a firecracker of a match, the underrated terrific kind Rollins had in the middle of his WWE championship run against Neville. As with Cena's open challenge, Rollins challenge could be a proving ground for a terrific talent in limbo like Gable.
