#1 Kevin Owens and Sami Zayn
Yep!
Owens and Zayn are officially on RAW, and they are a very welcomed addition. A tremendous loss for Smackdown, as the duo have spent the past six months as apart of the shows top feud, with Shane McMahon and Daniel Bryan.

They have managed to keep fans highly entertained with their antics, as well as being believable as major players with big victories over the like of AJ Styles, Shinsuke Nakamura and Randy Orton, among more.
The RAW roster is full of top stars that they can feud with as a team.
As mentioned earlier, like Ziggler and McIntyre, I don't think they should be used to challenge for the WWE Tag Team Championships, but instead feuding with one or two other major stars at the same time.
I would also like to potentially see an angle, perhaps an alliance with Ziggler and McIntyre, about being held back by WWE and the RAW General Manager Angle and other authority figures.
