Unless he hits the juice and gym plan, he's too short to be a real big star in the current WWE.Gable's WWE career will fall somewhere between The Blue Meanie and Chief Jay Strongbow.
He reminds me of someone like Keith Lee, who was an independent star and then the next big thing in NXT, but on the main roster Vince and his band of chicken sh** writers changed him and buried him.
I don't see Gable being any kind of amazing promo, so he'd have to get by on his in-ring work and that won't cut it as long as Vince is still alive.....unless he stays in NXT until Vince steps down/is gone.
Of course that's all assuming he even goes to the WWE anytime soon.
