Have a sit-down meeting with each position group. In that meeting, provide the players with a detailed listing of roles and responsibilities and have a clear and easily understandable picture of "what success looks like" for each group. Every drill that they do, every session in the gym, every film review session, there needs to be clear cut examples and milestones of what they will be expected to achieve every time they are in the building.

 

Convey to the players the true desperation of the situation. Something along the lines of  "if we don't all work together towards winning, we will be out of a job. If we're not prepared to attack our opponent, we will lose."

 

Or, you could just try and pull some tough guy [BLEEP] like OP suggested but I don't think it would do any good.
