#3 Austin Theory

Austin Theory is very new to NXT, but the heel has managed to get a lot of exposure in much less time. Theory started off as a babyface and got his first televised match against Roderick Strong for the North American Championship. While Theory performed his heart out in the match, he was unable to capture the title.
Theory turned heel recently and has even gone on to replace Andrade on RAW for the RAW Tag Team Championship match at WrestleMania. This proves that Theory has impressed the higher-ups in the company, and they seem to have a lot of faith in one of the youngest Superstars of the company.
If the brand is looking to build the Superstar on NXT and make him a top player soon, we could watch the egoistic youngster challenge Keith Lee for the title claiming he is better than The Limitless One.
Theory is extremely quick in the ring and the high flyer could give Lee a tough time, allowing fans to get some great matches between the two.
