I thought posting this previously was a giveaway that it was him but maybe he didn't have a sweet mustache when you stopped watching
Anyway, the good thing about AEW is I think most of their WWE imports have made sense. Most of the guys they've brought in either had recent star power coming in (Jon Moxley aka Dean Ambrose), were already established names people knew to help them get off the ground (Jericho, Matt Hardy) or people everyone thought had greater potential but were underutilized (Rusev/Miro, FTR/The Revival, Luke Harper/Brodie Lee)
That said, while I don't think they've "pulled a TNA" or anything, it's also a different wrestling landscape now. WWE has like 300 wrestlers under contract, almost everybody out there has been to WWE at one point or another.
