This is purely speculation, but how great would it be if the New Day switched team member combinations during the 2/3 falls Tag Team Championship match at Payback? Imagine Big E and Kofi start the match and they lose the first fall just to bring in the fresh Xavier Woods for the 2nd fall. They have been defending the belts using the 'Freebird' rule so why not add this to the mix? I think this would really get them some heel heat as it will look like they are cheating a bit here.
Also worth noting that at Elimination Chamber, imagine all 3 members of the New Day cramped into one pod. This would be hilarious to see the three of them cramped into one pod for a long period of time and can barely move.
I really think the New Days' heel turn and championship win has made them into one of the best things in the WWE currently. Especially mix in their rivalry with Kidd and Cesaro and they are must watch tv every week. Let's hope they can keep the momentum up and keep elevating the Tag Team titles.
