Most of the trades stayed within divisions. Top guy for top guy, jobber for jobber, woman for woman. This is the one case where that didn't play. The New Day going to Smackdown makes perfect sense. The Smackdown tag division desperately needed an established team to anchor the division. This works to reinvigorate that division plus reinvigorate a stagnant New Day who had nothing more to do on RAW. Plus, if/when they do break up, it allows three new superstars to enter the singles division. Meanwhile, I'm not totally sure why Bray Wyatt moved. There was still plenty left for him on Smackdown. He really had only feuded with Randy Orton, and both Luke Harper and Erick Rowan are still on Smackdown. Does he get lost in the mix on RAW? Potentially a huge move for RAW, but the fit isn't quite there. And it's an overall loss for Bray.
