#3 Christian
WWE Hall of Famer Edge made an incredible return to the ring earlier this year at the Royal Rumble, after satisfying WWE's doctors over the condition of his health. This gave hope to WWE fans about the returns of other Superstars who were forced to retire due to serious injuries, like Edge's good friend and former tag team partner, Christian.

WWE teased the same last month when Christian had an unsanctioned match with Randy Orton. Orton defeated Christian after Ric Flair low-blowed him, while The Viper landed a punt on Christian.
But, Christian hasn't been cleared to wrestle, which Sportskeeda's Tom Colohue revealed last month. He could, though, somehow be involved with WWE, in storylines involving Edge.
Christian hasn't been seen on WWE television since that match against Orton on RAW, but there's a possibility that he could be a part of Extreme Rules to take revenge on Orton, when the Legend Killer faces The Big Show.
It seems that we could get Randy Orton vs Edge Part III soon after the latter returns from injury, and Christian could be used to keep that feud going. Christian costing Orton the match against Big Show could all lead to that third match between Orton and Edge, sometime later this year.
