This was always obvious from day 1. He had no business winning the Rumble, no business winning the World title. He's always been trash in the ring. He moves awkward, uncoordinated, sloopy execution of movies, has no stamina, no good or standout moves, spams super kicks, etc.
He's 100% hit or miss on the mic. Sometimes he's had good promos. Other times he's been awful and he comes off like he forget his lines or don't know what to say when he has awkward pauses when he's pacing back and forth.
There's nothing to Jey but the yeet and entrance. Take that away and he's useless.
He's not a main-event star. But he would be fine in the mid-card. They should have let him have a legit good run with the IC title when he was at his peak popularity last year instead of using that title as a storyline ploy to get him back in the Bloodline storyline.
