1. Seth Rollins
Poor Seth Rollins. At WrestleMania 31, Rollins achieved his dream of becoming WWE World Heavyweight Champion. Cashing in his 'Money In The Bank' privileges, the man looked positively giddy as he held the belt aloft on the massive 'Mania ramp. Fast-forward to November, and the same guy was bleary-eyed and abject as he perched on the ring apron during a live event in Dublin, Ireland. Suffering a nasty leg injury, Rollins was forced to vacate the WWE Title and watch as others vied for the belt at Survivor Series. There were reports that Seth had been scheduled to drop the title to Reigns anyway on the pay-per-view, but that's missing the point a little. Even if that was the case, the wrestler had worked extremely hard during 2015, and surely deserved the chance to steal the show once more even in defeat. Reports suggest that Rollins will miss WrestleMania 32, which would have been a guaranteed major payday for the man. That's saddening, because a talent such as he would have helped make the show better. Some feel there's a slim chance he could be healthy in time to work a bout on the event, but right now he's entitled to be feeling just a little sorry for himself.
