Video: Zone coverage in focus

The Globe's Mike Reiss talks about the emphasis coach Bill Belichick and the Patriots are putting on their zone defense during the bye week. Click the "full entry" link below to watch the video or check out the written summary.

Written summary:

• Bill Belichick had a long list of items the Patriots will be working on this week, and he revealed that one will be pass defense, specifically in zone coverage.
  
• While the Dolphins had success in their "Wildcat" package with Ronnie Brown taking the direct snap, they also gashed the Patriots in the passing game with Chad Pennington. The Patriots seemed to be loose in their zone coverage on those plays.
  
• A big part of zone coverage is that each defender trusts that the next defender will be in his proper area. If that trust isn't there, defenders can sometimes try to overcompensate and do more than what it assigned to them.
  
• The defense will look to build up that trust over the next two days.
