The first three don't have to be the HC, if we get an OC with those that'd be awesome. The HC needs to manage the team and coaches. Be aware of all of the rules, health and conditioning of the players. Make sure the players and schemes fit. Make sure the coaching staff is working together. Make sure the game plans are appropriate. Coordinate the practices and training camps. In game, manage the flow, clock, momentum, and morale of the players.
