#4 Feud with Finn Balor
Whenever we're done watching an NJPW pay-per-view, we're often at a loss for words with regard to the in-ring action that we witness from the talented performers. WWE too has some of the best independent wrestlers in the world today. They too can go at a million miles an hour, if they are allowed to. The Usos and The New Day have proved that, time and again.
By having this babyface vs. babyface program, WWE would be pleasing the hardcore fans who've wanted Rollins and Balor to be used to their full in-ring potential. It would also be interesting to see how Gallows and Anderson could influence the match-up. The possibilities are quite endless.
Another possibility could have Finn Balor turning heel, to give his character a fresh coat of paint. We've not seen this side of Balor's, and would certainly love to.
It would be fun to possibly see the Demon return, as well.
