#4 Sami Zayn
A few injuries have kept Sami Zayn from reaching his true potential, but when you look at the history of WWE's world title holders, it seems wrong to not see his name on the list.
Zayn was ready for the main roster long before he was called up, but WWE took the slow approach to building his character in NXT as the ultimate underdog. He was being groomed as the next fan-favorite, but a shoulder injury delayed his main roster debut by almost a year.
Zayn has watched friends he has known from the indy scene for over a decade being pushed past him, but no matter how many times WWE stalls his push, Zayn continues putting on show-stealing matches.
The crowd loves him, and his feuds with competitors of all shapes and sizes prove that he can have a good match with anyone. He should be considered for the WWE or Universal Championship in 2017. Anything else is unacceptable.
