For the 2009-2010 season it was the Pittsburgh Steelers in terms of points, and the the San Diego Chargers in terms of yards allowed.
Steelers--period
which nfl team runs a 4 3 defense
The Pittsburgh Steelers. No question about it!
Brian Urlacher
probably the steelers.
Steelers and Ravens
The New York Jets had the best last year, though the best defense in the league statistically shifts every season.
Currently, they are not the best team in the NFL.
Dallas Cowboys Best Team
Pittsburgh http://www.nfl.com/stats/team
The Boston Celtics have the best defense because you need defense to win championships and they have 17
There is not a chance in the whole world that the best college team beat the worst NFL team!
