#2 Should be - Apollo Crews
Apollo Crews has failed on the main roster thus far, but it seems like the WWE Creative are trying hard to rebuild him. Given the talent he possesses, he could certainly feature in the mid-card or upper mid-card matches on RAW.
The former member of Titus Worldwide defeated the former WWE Champion, Jinder Mahal, in under 3 minutes on the previous episode of RAW.
Crews is one of the most athletic and flexible superstars in the ring who can pull off some of the most mesmerising moves in wrestling.
He should have received this push earlier, and given that Elias has issues with Corbin, there's no other superstar on the RAW roster who deserves a chance than Apollo Crews. Even if he is eliminated first, his involvement in this mega match-up would elevate him to the next level.
