A debut for Sting on the night after WrestleMania 30 would make most sense. WWE traditionally use the post-Mania Raw as a launch point for a big angle, so it would be smart this year to help get Sting over by debuting him on the April 7th Raw in a challenge to Undertaker. That's the match expected to take place at WrestleMania 31 according to the Wrestling Observer. If it gets established a year out on Raw then it would be a note-worthy moment for the WCW star getting off the mark on a hot segment. If that doesn't happen, then WWE can really pull the trigger at any point through the rest of the year. Springtime into summer can be a bit barren up until Money In The Bank, perhaps Sting should debut during the quiet period of June to add some value and interest. There's also got to be a good chance Sting debuts at WrestleMania 30 in some sort of angle. He will be in New Orleans over the weekend for the WrestleCon event, he could easily stay for something on the Sunday. Many fans have stated how cool it would be to see Sting re-use his old WCW gimmick of descending from the rafters on a rope. That would certainly be a great visual debut, but is unlikely given the Owen Hart tragedy with a similar gimmick.
