That has always been the rasslin' business. Except for Flair, and maybe Jerry Lawler, outsiders weren't going over Verne Gagne's, Bill Watts's, Fritz Von Erich's, or Jim Crockett's top guys, either.Not sure why any actual stars outside of the WWE system would want to fukk with knowing the decades of how WWE treats outside talent in their working relationships even going back to the 70s. At best, a win over Ziggler.
Outsiders usually get fed a few jobbers, a midcarder or two, and then put over the promoter's top guy. It's pretty much always been that way.
