The Packers have Woodson but their linebackers are

better than their corners. 

NFL has turned to pass-happy league (thanks to millions of stupid rules that limit the role of defense) but most of the teams want to establish running offense (excluding teams like Andy Reid led Eagles).  The Giants is not exception.  The problem is that the Giants offensive line is declining & they can't get a push or create holes for the running back to run through. 

The ideal scenario is that the Giants can get their ground game running, which keeps the other offense off the field, when they face the power houses.  The offensive line is the key.
