6. Cesaro
Speaking of superstars who've slipped under the radar since sustaining injuries, we're all slightly guilty of forgetting about WWE's own Swiss Superman. Despite suffering from bad booking, Cesaro was on the roll of his life in 2015 (at least in terms of fan support). The former Chikara star has recently stated that the injury looks set to keep him out of WrestleMania 32, and that he's even changed the background of his phone screen to read 'WrestleMania 33', giving him a different goal to work towards. Of course, this is the world of professional wrestling, and you have to be wary about everything you hear. A return at Fastlane would likely be very well received, especially by a slightly smarkier PPV crowd. Regardless, whenever he does come back, it could be the start of the push Cesaro truly deserves.
