You mean the 2005 Super Bowl winning Pittsburgh Steelers that had a top 5 ranked defense in both yards and points allowed?

You mean the Willie Parker that ran for 1200 yards that same year?

Or how about the 2008 Super Bowl winning Steelers defense that was #1 in both yards and points allowed?

What about the 2001 Patriots that had a 1100 yard rusher and rated 6th in points allowed? (i'll admit they were rated low in yards allowed)

The Ravens had a middle of the pack defense,

but they had an 1100 yard rusher too.
