#2 Lars Sullivan
Lars Sullivan is one of the top prospects in NXT today; called the Braun STrowman of NXT, Sullivan is a Monster Among Men in his own right.
Even though Sullivan was unsuccessful in winning the North-American Championship at NXT Takeover: New Orleans in the 6-man ladder match, he impressed everyone with his performance.
Much like Strowman, Sullivan is gifted with not only strength but also agility and swiftness when it comes to in-ring action and the two would be perfect competitors for each other.
It would also make RAW more exciting with another high-profile NXT call-up.
