Bryan
Great speech he gave and wouldn't be surprised if WWE puts him in the Hall next year like they did with Edge's sudden retirement. If Brock or Rock don't go in next year, Bryan easily headlines that class.
His Mania 30 moment was really bitter sweet in how quickly it went from an amazing high for him (winning the title) to a terrible low (both his father and Connor passing away shortly after the event) and then got even worse (injured a month later).
