#5 and #4 Luke Gallows and Karl Anderson
While Gallows and Anderson had a great debut when they destroyed the Usos, they were underutilized since then and are treated like jobbers even though they have a lot of recognition as a top team. They competed in the last Andre the Giant Memorial Battle Royal and will likely do so again.
#3 Rowan
Rowan recently made a return at the Royal Rumble and became Daniel Bryan's ally and sidekick. Since then he has not been pinned or submitted. While he will likely be at ringside for Daniel Bryan's match for the WWE Championship (which will likely be against Kofi Kingston). However, before that he will likely compete in the Andre the Giant Memorial Battle Royal.
#2 Shelton Benjamin
Shelton Benjamin has arguably not been utilized well since his return to WWE. He barely appears on TV and when he does, he is normally losing. His last televised victory was months ago against Daniel Bryan. He will likely be in this battle royal once again and will be one of the veterans of the match.
#1 Harper
Harper was recently cleared to return to competition and defeated Mojo Rawley at a live event. While he has not returned to TV yet, he is bound to do so soon. When he does return, he will likely be a part of the battle royal where he can face off with fellow former Wyatt Family members in Rowan and Braun Strowman.
