#1 Edge
Edge had one of the most memorable retirement speeches of all time, on the episode of RAW after WrestleMania 27. Many believed that Edge would never be cleared to wrestle and compete in a ring again.
However, last year Edge would Spear Elias during Summerslam and rumors began that he has been cleared. Also earlier this year it was reported that Edge has signed a new five-year deal with the company. We have reported numerous times on the Rated R Superstar and his potential return to the ring and if he does it will certainly be memorable.
The reason it could also be his last is due to his age, health and status in the company. The injury concerns are still very apparent even with a clean bill of health and a return to the ring.
It's also very unlikely he would return for a full-time run and with him being able to compete just on occasion another Rumble match may not be in the cards.
