#2 Drew McIntyre
Drew McIntyre, who was once part of 3MB, left the WWE to work in other promotions. He worked harder than ever, improved his ring-work and promo skills and made a name for himself outside of WWE. He made his return to WWE as part of NXT. He became the NXT Champion and was one of the most dominant NXT Champions.
Drew McIntyre debuted on Raw as the partner of Dolph Ziggler and helped him become the Intercontinental Champion. McIntyre and Ziggler are currently the Raw Tag Team Champions and are feuding with The Shield recently with Braun Strowman as their partner.
Mcintyre hasn't been pinned in a match ever since debuting onto the main-roster scene this April. This shows that WWE is protecting him and see a future superstar in him. Winning the Universal Championship could certainly boost his career to the next level.
