#3. Bray Wyatt and Daniel Bryan have unfinished business
Bray Wyatt and Daniel Bryan have stepped into a feud on WWE TV before, a feud that ended somewhat prematurely and many fans didn't agree with the way that it turned out. Wyatt tried to force Bryan to turn his back on the WWE Universe and join The Wyatt Family, something that he did for just one week before he decided to once again turn face.
Wyatt's mind games have improved since then and the premature ending to their feud could mean that it could be picked back up again a few years later and allow Bryan to be one of the first followers of The Fiend in his new form.
There is a reason why Wyatt is able to play mind games and why he chose to take the fight to Daniel Bryan and now that Bryan has accepted, there could be much more to this storyline to the point where it could now continue well into the new year. A win for Wyatt at Survivor Series would mean that he's been able to overcome the threat of another one of WWE's biggest stars.
