#2 - Edge

Edge is one of the most popular WWE stars of the modern era, and even though, in my opinion, he was far better as a heel than he was as a babyface, I think he'd make for a great babyface general manager.
Unlike with everyone else on this list, I think that the fans wouldn't expect Edge to wrestle another match because of how his career ended. Also, most of the WWE fans probably know that if he could've come back for another match, he probably would've by now.
Look who just shut down all of Tony Khan's critics! More HERE.
They could also bring in Christian, who is also retired, to be the co-general manager on Raw since the two have great chemistry together and would probably be very entertaining in the role.
