#1. Ricochet

Ricochet has lost a lot of momentum over the last one and a half months following his unsuccessful challenge of the WWE Championship at Super ShowDown against Brock Lesnar. His loss in 2-and-a-half minutes meant that he was right back to where he started.
After WrestleMania 36, it was confirmed that he would be in a tag team with Cedric Alexander - another Superstar who lost significant momentum last year. With Ricochet, however, many believe that he has what it takes to be a future World Champion.
While his in-ring performances are incredible, his biggest drawback is in the character department. There's no doubt that he has what it takes to reach the highest level, but it's a long way to the top for him.
To begin with, Ricochet doesn't seem like the kind of character the MITB briefcase suits. Even otherwise, he's the kind of uperstar who needs a slow but steady build before eventually getting pushed to win the MITB.
Ricochet is a future World Champion, but he's far from ready right now.
