#3 Apollo Crews
Apollo Crews looks like a million bucks. The guy looks like a freight truck, but moves like a sports car. Nobody is suggesting that he be slotted into the main event picture, he is surely too good to be wasted on the main event.
Titus worldwide is finished, and even if it wasn't, it is never going to gain any sort of traction as a tag-team with the likes of Dean Ambrose and Seth Rollins, Drew McIntyre and Dolph Ziggler, and AOP around.
SmackDown Live desperately needs babyfaces. Crews would be a fine addition to the mid-card. He could fight Andrade 'Cien' Almas. Maybe he could be used to keep The Miz away from Daniel Bryan.
At the very least, he could serve as a challenger for Shinsuke Nakamura's United States Championship for a pay-per-view cycle.
