re: WTF is a passing game coordinator?!

Having a passing game coordinator and having co-coordinators is basically the same thing. It's a way of cutting the game day preparations in half. One coordinator comes up for a game plan for the run game and the other only focused on passing attack. They then meet and come up with a complete game plan and share it with the team. That's usually why most teams with CO coordinators are the rb and qb coach.
