So just program it so it kicks in for the team trailing. As I said before though if you don't want to run the no huddle under 2 minutes give us an option to huddle up and thus accelerate the play clock.
The final 2 minutes of each half in madden would be so much more rewarding if it was more strategic..........play calling, field position, time left in the game. If you're in control of the game and have the ball it'll speed the game up more and add more strategy to user and ai opponent timeout usage as well as stopping the offense and getting the ball back.
I see what you're saying though, right now it's so bland
