#4 Elias

Despite not doing much with him, Elias remains one of the most over WWE Superstars. Few can match his ability to work a crowd. This skill makes him a valuable commodity, and he's managed to get just as over as a babyface as he did as a heel. The transition was seamless.
Elias is a guy that's just begging to get a championship run with a mid-card title. If WWE doesn't capitalize on him and give him a bigger push than he's gotten, they would be foolish. It's time to put his act into more extended storylines, rather than just stand-alone skits.
Look who just shut down all of Tony Khan's critics! More HERE.
I'm usually not optimistic when it comes to the main roster, for good reason, but this seems obvious. Albeit, Elias is a dark horse, but I think he'll secure a run with the Intercontinental or United States Championship at some point in 2019.
