Give him the right manager and he'll be a Upper Carder and World Champion on the main roster. He's got the Monster Heel "it" factor. Not only is he very athletic, but he has a presence about him. His African Prince gimmick works well. Pretty much, his ceiling is the African Brock Lesnar who can talk on the mic decently.

If there's anyone on the roster right now who could be that manager, it's MVP, unless Paul Heyman for whatever reason didn't want to keep doing programs with Roman, Brock, Punk, Solo, etc. and wanted something fresh.
