Fred Pagac wanted to enter the 2011 season more aggressive on the defensive side of the ball, and he did just that in this contest, with mixed results.
The Vikings managed just two sacks, but did get four hits on Rivers and intercepted him twice. They had him running around all day long.
The problem was, though, when the Chargers changed their offensive approach, Pagac never adjusted.
The Chargers had trouble stopping the blitzes and pressure from the Vikings, and also had trouble breaking through the coverage packages, which caused them to adjust.
San Diego abandoned the deep-ball focus, and reverted to throwing the short routes underneath to Mike Tolbert and Antonio Gates.But the Vikings never really adjusted to the Chargers adjustment, which was one of the main reasons for the loss.
It's a minor observation; one that can easily be fixed in Week 2.
