#3 Rusev
No matter when he shows up or how he is booked, Rusev will likely always be over with the fans.
His 'Rusev Day' gimmick isn't on par with the 'Yes Movement' but it's another sign of a wrestler who got over organically with the crowd.
He had great matches with Chad Gable, AJ Styles (for the title), Andrade Almas and Bryan himself, and always delivers in the ring.
He hasn't had a huge role lately on Smackdown but could easily be thrust into the main event for a feud with the American Dragon.
Bryan can compare the 'Yes Movement' with 'Rusev Day' and say that its time is up once he defeats Rusev. He's one of the few wrestlers that might get the entire crowd to cheer for him against a heel Daniel Bryan.
The clock is ticking on Rusev as a WWE wrestler. He's stated his frustrations with his place on the roster several times before and he might not be the most-loved guy backstage by creative anyways.
They still probably hold the whole 'engagement to Lana' fiasco against him as well as the flip-flopping of facing and not facing the Undertaker at the Greatest Royal Rumble.
If creative just stuck with him during the height of the 'Rusev Day' gimmick, they might have created another main-event star.
Instead, it might have run its course with the Aiden English feud.
