5 WWE Superstars who were promoted from NXT too soon 

#4. Current WWE NXT Superstar Austin Theory

Austin Theory came to WWE through the company's connection with Evolve, where he was a former world champion. Theory wrestled several matches for developmental before he was called up to the main roster and was aligned with Zelina Vega.

After failing to get along with Andrade and Angel Garza, Theory was kicked out of the group and was later recruited by Seth Rollins where he became one of his disciples. Of course, the WWE Universe will be aware that this was a union that didn't last very long. Theory was named as one of the stars in the #SpeakingOut movement and was then taken off WWE TV.

There was no update on Theory or a reason given as to why he had been taken off TV. He later resurfaced back in NXT. It appears that it was too soon for the star to be promoted and since his return to NXT, he has found his feet with Johnny Gargano and Candice LeRae as part of The Way.
