#2 Matt Hardy
It's quite a surprise that Matt Hardy - and his brother, Jeff - are still wrestling in the WWE after years of taking bumps and high spots, while also being a victim to substance abuse and alcoholism.
The Hardy Boyz revolutionized tag team wrestling in the WWE, inspiring future Superstars, wowing audiences, and making tag team wrestling an important division in the WWE.
Matt teased his retirement when he split with Bray Wyatt, but has now returned to team with his brother once again, but this current run may very well be his last one in pro wrestling.
Maybe we could one last Hardy Boyz classic match at WrestleMania 36, against a team like The Revival, or Ricochet and Aleister Black (if the team still exists till next year), or even The Usos. Any one of those teams with the Hardy Boyz would tear the house down and give Matt Hardy a fitting finale if he does leave the WWE.
