#4 Sami Zayn
SmackDown has some of the best mic workers in the industry, and Sami Zayn is one of them. Zayn has been Shinsuke Nakamura's mouthpiece for some time now and has given up competing in the ring for the most part.
Last week on SmackDown, when most of the roster was stuck overseas, Zayn stepped up to talk against NXT and their invasion. He'd pay dearly for his remarks, as he was chased into the arena by Matt Riddle and Keith Lee, who then proceeded to flatten the Superstar with some impressive moves.
This week, we could see the loudmouth express his anger at being targeted by the NXT roster. He could talk about how he single-handedly stood up for the Blue brand while other Superstars, along with the Universal Champion Bray Wyatt, were busy vacationing overseas.
This could bring out The Fiend once again to attack 'The Critic of Critics,' as fans love to see Zayn get what's coming to him. The attack would keep The Fiend in the loop and in front of the WWE Universe in case the company decides against booking him for a match at the upcoming Survivor Series pay-per-view.
