#2 Daniel Bryan

Logic would suggest that the WWE's plan for Daniel Bryan at WrestleMania is to have him dethrone The Miz as the WWE Champion, putting an end to their on-going feud once and for all.
The WWE has seemingly lost a bit of interest in the feud between the two men though, and following his decision to not attend Crown Jewel last week, there is every chance that the WWE might feel as though they can't rely on Bryan to carry the belt, especially if they intend on returning to the country for a post-Mania show, as they did this year.
The two former colleagues have already had a little bit of a run-in on the most recent episode of SmackDown, and given that the WWE teased a feud between the two men last year, this one really wouldn't prove all that difficult to set up.
