#1 The Hardy Boyz reunite to challenge The New Day
The New Day has pretty much run through the entire division and one wonders who's next for the pancake-loving duo. Heavy Machinery would be ideal but both teams are so beloved that a babyface vs. babyface feud simply doesn't make much sense.
I could say that a Hardy Boyz vs. New Day feud is something that fans can invest their time and energy in, and it could certainly be set in the final SmackDown of the year. Jeff Hardy is slated to return at any time now and Matt Hardy has been putting younger superstars over on RAW.
The Hardy Boyz could really bolster the Tag Team Division and maybe even carry the titles all the way to WrestleMania. If they trade victories with The New Day, it'll help Big E and Kofi Kingston increase their number of reigns.
Plus, it's a fresh feud and one that fans would love to see!
