1) Damien Sandow
It’s amazing that Damien Sandow hasn’t answered the Us Open Challenge as of now. This man was one of the most over performers of 2014, but hasn’t had a great 2015.
Wrestling fans do remember, and Sandow hasn’t done much of anything since Wrestlemania 31. A surprise return for Sandow and his first single’s championship would be a wonderful way to catapult him back into prominence and give him a real chance as a WWE star.
