#7 Billy Gunn
When Billy Gunn signed with AEW, no one expected the 56-year old WWE Hall of Famer to wrestle with the current AEW Roster. Most thought that he would be more of a backstage producer helping the current crop of young wrestlers in a producing capacity. But he did so on an episode of AEW Dynamite in the Diamond Dozen Battle Royale.
Even more interesting, he teamed up with his son, Austin Gunn on an episode of AEW Dark. It was also announced that Austin has been signed to the promotion and it's very possible that they could be teaming up in the near future as Gunn trademarked 'Gunn Club' very recently.
#6 Triple H
Triple H is like a dependable car that keeps chugging along, aggregating miles on its body, but still managing to hang in there. That may sound like a putdown to Triple H, who is now 50 years old, but it's actually a compliment. Triple H came of age in the WWE's Attitude Era and has been able to stay relevant all these years.
Triple H may have taken a backstage role as he's gotten older wrestling only a handful of times in the year. He has never missed a WrestleMania and it's highly likely he will not miss this year's Showcase of the Immortals. Like The Undertaker, he has become synonymous with WWE's Flagship PPV and it'll be interesting to see who his opponent will be.
Perhaps, someone from the NXT brand? Only time will tell.
