I honestly don't think there is anything you can do defensely to stop the pats. Brady juat doesn't hold on to the ball longer then 3 seconds. The only issue I see with their offense is their not a big play offense. Its death by a 1000 paper cuts and the only way to limit that is to play sound red zone defense and make them kick FGs.
For the Rams to win they have to do three things:
1) Donald, Suh, and Fowler providing consistent pressure. That and this would surely limit New England’s run game too.
2) Get Todd Gurley going. Use CJ Anderson in short yardage situations.
3) Win the time of possession.
