#4 Shinsuke Nakamura
Speaking of Shinsuke Nakamura, another popular figure in WWE upon his arrival to the main roster from NXT. Just like every other NXT star, the company failed to utilize him properly. They kept pushing him to the main event scene where he kept losing until he turned heel during his feud with AJ Styles. From there his fall down the card began.
Even now WWE can change all of the mistakes they have made with Nakamura's character by turning him into a babyface once again. This would not only help Nakamura to climb back to the main event picture but also increase the declining WWE TV ratings. Also, it will keep Nakamura with the company for the foreseeable future.

#3 Ricochet
Before his arrival in WWE, Ricochet was one of the most popular indie stars in the wrestling business. His in-ring performance along with his character was beloved by the fans around the world. Ricochet had a short run in NXT before getting called-up to the main roster around three months ago.
He was one of the participants in the men's Money in the Bank ladder match this year but couldn't win the contract. The company cannot waste a talent like Ricochet, they have to properly give him a solid push. Maybe firstly in the mid-card scene and then slowly push him to the main event scene. He can definitely bring in some indie fans to the WWE TV.
