I told you guys after Cody lost to Roman last year that he's not dethroning Roman, but everyone was like oh they are gonna use entire year to book Cody look stronger so that next Wrestlemania he finally dethrones Roman
Cody is not winning undisputed championship just like Phil next year is not main eventing Wrestlemania night 2. Once you leave WWE for another company they're gonna find a way to mess with you. It's almost the same as all those non-WWE talents who went to WWE and didn't win shyt. AJ is the only exception because he's one the best in ring performers ever. And even him after 2016 he has been underbooked by WWE.
WWE is barely building their wrestlers outside of Bloodline story. If Stone Cold and Undertaker weren't injury ridden old men and if Rock wasn't in Hollywood, they'd be bringing back these guys for several PLE's.
