#3 Luke Harper
Luke Harper is one of the most talented big men that WWE have ever hired, and his run in The Wyatt Family was fantastic, but since the disbanding of that cult-like group, he hasn't found his footing in WWE.
He continues to prove just how great he is inside the ring, but for some reason, WWE just don't want to bring him back as a singles star, so a trip back to NXT to prove to WWE management and the world how good he is makes sense.
Harper is a very versatile performer, meaning he can work different styles with many different types of performers, so matches with varying opponents like Keith Lee, Matt Ridlde, Johnny Gargano and so many more would be must-see.
He was once down in NXT during the very early Full Sail days, and he'd be treated like a king upon returning, so we'd very much like to see him have one match or one solid run in 2019.
