‘Teams can gain a lot of advantages using motion. It helps reveal the defensive scheme. If no defenders move with the motioning receiver, they’re very likely zone coverage. Motion forces the defense to communicate more, which could create a coverage bust. It can create a numbers mismatch in the run game. It can create a mismatch in the pass game (if a team with one top cornerback doesn’t have that guy follow the star receiver). It can help get a receiver off of press coverage.’
