#2 If Kofi loses, New Day breakup
The New Day are the reason why Kofi Kingston is heading to WrestleMania to face Daniel Bryan and the chairman would not be a happy man. To make sure that such a thing never happens again, he needs to break up the faction but without messing around with them.
The WWE Chairman can easily add a stipulation to the match at WrestleMania and make Kofi put everything on the line. If Kofi loses, there will be more of New Day in the WWE.
The trio spoke about quitting recently and going by what Vince has done in the past, it won't be a surprise if he not only says that they break up, but their WWE futures depend on the match result.
This was done with Team Cena vs Team Authority at Survivor Series in 2014, and to make things more interesting at WrestleMania, Vince might replicate it.
