#2 Daniel Bryan
Daniel Bryan is a man whose popularity made WWE change all their major plans for the grandest stage of them all, Wrestlemania. Even when not wrestling, "The Yes!" man manages to get the loudest reactions from the crowd.
Daniel Bryan's rise to fame started after Wrestlemania 28, where he lost the World Heavyweight Championship to Sheamus in 18 seconds. The World's Toughest Vegan feels he still has wrestling left in him but WWE might not allow him to risk his life.
Bryan has stated that many doctors have cleared him to return to in-ring action. However, WWE doctors are yet to give the green signal. Although it is too greedy as a fan to ask D-Bry to do something which could really hurt his body, one can not rule out the chance of seeing him wrestle, if only for one night.
