Throughout the last decade the NFL has seen a shift in offensive philosophy. The goal is no longer to establish the run, and eventually open up the passing game, but now has turned to using the passing game to move the offense down the field.
You can’t blame the change of approach considering the rules put in place to protect the quarterback and receivers.
But even though the game might be changing doesn’t mean defense has been making such a drastic shift in overall philosophy. The athletes who are deployed, and the packages they use, might have changed, but for many, including Pittsburgh Steelers’ defensive coordinator Keith Butler, the goal remains as tried and true as always.
