#9 Sami Zayn
Even though Sami Zayn is going through a highly rough patch as a heel on Monday Night Raw (Seriously, what was that Lashley's sister's segment?), there is certainly no denying that he is one of the smoothest workers in the ring.
One of the few natural babyfaces, Sami made a successful transition to the negative side last year.

However, Sami was not always, well, Sami. During his stint outside and before his arrival at WWE, Sami was El Generico, a luchador from Mexico.
His tenure in PWG and ROH, which included a phenomenal feud with his friend-turned-enemy Kevin Steen (now known as Kevin Owens), earned him critical acclaim from fans.
Even though he is yet to win a title in WWE, Sami held various Championships during his tenure in other promotions.
He is a two-time PWG World Champion, five-time Tag-Team Champion in PWG, in addition to winning both of their annual tournaments. In ROH, he won the ROH World Television Title and Tag-Team Title with, you guessed right, Kevin Steen.
