#1 Zayn deserves and has earned the opportunities

Whether he is billed as an underdog or the little engine that could, Sami Zayn can tell a story in the ring like very few on the roster. The company has seen this, and while they may be pleased with the commitment that Jinder Mahal has shown after his move to Smackdown Live, it is different for Zayn.
His commitment to his craft and willingness to put others over shows a lot of character, and how good he is both inside and out of the ring. The upper management has seen his ability to make others look good, and the move suggests that they are rewarding him for his dedication and hard work. By overcoming injuries and setbacks, Zayn could easily be said to have earned a better spot, and a bigger role on television.

Raw in comparison appears somewhat saturated with talent, and Zayn didn't fit in. Being on Smackdown Live a few years ago would have been seen as a kiss of death, but in the case of Sami, it should be looked at as breathing new life into his career.
