#2 Shawn Michaels
Shawn Michaels and Daniel Bryan have quite the history together. Shawn Michaels was retired when a confrontation between teacher and student was teased the last time around. We know that he is an active competitor now based on his performance at Crown Jewel.
And this makes me believe that WWE wouldn't be opposed to a match between Bryan and Michaels. Both men are two of the greatest ever and they could tear it up inside the squared circle. Michaels has said that he wants to compete with fellow legends, but he may make an exception when it comes to Daniel Bryan, because of their past.
In fact, Shawn Michaels is a hunter and we know that Bryan is all about preventing animal cruelty. I believe we're heading in this very direction. And how good will the match between these two men be!
