#4 Let him join the Tag Team Divison:
At the moment it's all about giving Crews as much exposure as possible, him being in a tag team gets a foot in the door. Pair him with an unlikely partner like Curt Hawkins. The same way an unconventional pair like Rhyno & Heath Slater got over, Crews & Hawkins could be the next big thing.
Nowadays, if you put on good matches and have a chant that is easy to understand, you get over. Apollo in a tag team would have no chance of being overexposed. Instead, the spotlight would be evenly shared by the pair.
Tag teams provide interesting dynamics because their numerical advantage allows them to perform moves that we don't see week in week out. Also, if one botches a move, the other could cover for them. Being in a tag team protects Apollo as he doesn't have to talk every week or wrestle every minute of a match.
