They have no idea what to do with them. Can only end in two ways; good or bad.

this prediction will either be right or wrong
I'm with
@Ed MOTHERfukkING G on this one. This isn't the best use of them, but with how they've been booked since they lost the titles, I don't think they would get anything meaningful together in time for Mania. They dominated the tag division for so long that it if they aren't going for the titles, it's beneath them in a way.
I love the New Day and at this point, they should all be wrestling solo more with the other 2 out there with them. Theres no reason Kofi or Big E can't be built up to get a shot at the title or at least be in the mix. They will be over enough for the fans to buy into it and I think they would genuinely want any of those guys to win. For as overplayed the You Deserve It chants are, Kofi is damn near at the top of that list. Mania may be a let down and hopefully not the black guys welcome back Hulk host job, but the fans will enjoy everytime the New Day is on screen or in the ring.
