Belichick adding emphasis to defense

New England Patriots observers have been curious how Bill Belichick is going to handle not having any coordinators.

Belichick has insisted coordinator merely is a title and he won't be stretched too thin by not designating his top lieutenants. He still hasn't promoted anyone since former offensive coordinator Josh McDaniels departed for the Denver Broncos a year ago. Defensive coordinator Dean Pees stepped down after last season.

More than usual, eyes were on Belichick when the Patriots held their first open team workout. Belichick spent a predominant amount of time overseeing the defense.

"It was one of those moments that created little doubt as to who was in charge," ESPNBoston.com reporter Mike Reiss writes.

Reiss notes that while Belichick ran the defensive drills, quarterbacks coach Bill O'Brien and offensive line coach Dante Scarnecchia seemed to have command over the offense.

With an overview of the defense, Reiss explains why Belichick's increased involvement is critical. The Patriots have a young defense and uncertainty at various positions. The Patriots especially need to generate a better pass rush.
