Opposing Gamebreakers on defense
If your opponent has a defensive Gamebreaker, the best thing to do is set up a shotgun then throw quick passes. Throw the passes immediately after the ball is snapped because you will not get hit and fumble the ball for the other team to get great field position, or even worse a touchdown. Also, you want the other team to waste their Gamebreaker.
Recommended players
Choose the Falcons for quick game mode. First, choose first Keith Brooking, the hardest hitter. Next, pick Patrick Kerney, a defensive linemen. Select Michael Vick and either Warrick Dunn or TJ. Ray Buchanan and Bob Whitfield make a even better team. Finally, choose Peerlice Price, one of the best wide receivers.
