Adjustments during the game

The best example I can offer is the Chargers vs Steelers this year. In the first half, the Steelers curtain was tightly shutting LT's run and led 10-3. They boxed the front and dared Rivers to throw. And he did and won the game by his throwing. Strange to say, the Steelers never made the significant adjustment in the 2nd half to counter Rivers' throw, maybe they tried but failed. They wold probably do the same thing to the Saints in the first half.
