#4 Kevin Owens and Sami Zayn
Ever since Kevin Owens moved to Smackdown Live he hasn't been in top form. The lacklustre feud with Shane McMahon did not help.
Sami Zayn was then added to the mix which finally resulted in a Wrestlemania match. Even that got overshadowed by the returning Daniel Bryan.
Corey Graves deleted his Tweet! More details HERE.
Zayn has done some excellent work a villain along with Kevin Owens. The two are a great pair that can add value to the Raw brand.
Technically they are not part of shake-up since they were fired from Smackdown and hired by Stephanie McMahon, nevertheless, we consider the move and WWE have decided to bring them back as part of the shake-up.
Much like the BAR, Owens and Zayn are the best either way - they are great assets individually or will be used to make the Raw tag team division something to watch out for.
