He'd be a big fish in a small pond in WWE developmental, think...
Lee, Cole, Fish, O'Reilly (two of which didn't make an impact in AEW, and Fish, who went to impact)
Gargano, Ciampa, Kross (Ciampa been Mia, Gargano is injured, Kross is in a feud with Mysterio that is boring)
He doesn't have a big enough name To pull a Cody, dude came back and kept the same everything...I doubt Whomever is in charge of creative when White contract is up would do a Dundee gimmick, but he definitely ain't gone be doing what he did in Japan
Maybe he goes to Aew, a private company, and aligns with Juice Robinson. And then what, more bullet club and too sweet equals another stable/faction...Khan isn't booking White to win the Aew world championship...hell he didn't even put the belt on Danielson when he signed
He'll be better off in Impact, since he actually got heat/over unlike some NJPW guys who went to TNA/Impact and flopped....
