#4 Juice Robinson
Joesph Robinson took a big gamble when he asked for his release from WWE in April 2016. As CJ Parker, Robinson was used to put over NXT's newest marquee signing.
Despite his lowly status, he was well-liked by NXT management and was featured on NXT's weekly programme often (losing). CJ Parker had little name value outside of NXT, his prospects on the indies looked grim.
Against all odds, he has prospered on the indie scene. Shedding his CJ Parker gimmick and reverting to the Juice Robinson name he debuted with, Robinson has reinvented himself. Last year was his breakout year in NJPW, he challenged for numerous titles and had a strong showing in his debut G1 Climax.
Whether he should switch in 2019 is debatable. He's likely to win one of NJPW's singles titles this year after coming up short last year. This is Robinson's fourth year in NJPW, at this point he may be tired of the constant long journeys to Japan. NXT's light schedule must be looking mighty appealing now.
After tangling with Tanahashi, Omega and other high-level stars, Robinson has drastically improved since his CJ Parker days. Ironically, if Robinson were to return to NXT, he would be one of those marquee signings that he used to lose to every week.
