Nah. This ain't Cena/Roman.
This is 1st WWE-run Drew McIntyre.
And like Drew, best thing Theory can do is disappear, and reinvent. The hairless body guy without any grit and the 'chip on his shoulder' as the only character trait... shyt ain't gonna work. Mans desperate needs and edge he will not be able to get at this point in WWE, and the longer he's stood by Waller the more the charisma delta between them is going to bury him by association.
That he's a better worker, in better shape and had more push than Waller and still ends up being second fiddle is going to kill him completely dead. And sending him to NXT for rehab ain't gonna work at this stage.
Mans needs a reboot. Send that nikka on excursion on some NJPW shyt, and when he comes back from whereverthefukk in 2 years with some hair on his chest, figuratively and literally, maybe people will be ready to accept him. But at this stage, he's pretty much just going to get buried under the wave of NXT callups that will expose him horribly.
Thing is, he's on a timer. If he can't get some bass to his character before Trick learns to work semi-compelling 10+ minute solo matches, cue the Vince Carter gif. Bron, Melo and even Ilya are already better characters and workers at this point. That young up-and-comer main roster scene about to get wild crowded.
The big hooplah over his signing from Evolve seems like a decade ago
