"The playoffs resumed this weekend with the possibility of a historic matchup in the Super Bowl pitting the NFL's worst two defenses.

Yes, No. 32 Green Bay vs. No. 31 New England.

And where is the No. 1 defense? Home, after losing for the first time in the playoffs to a team without a winning record, a team with the No. 23 offense and No. 20 defense.

The Steelers had the No. 1 defense in 2011, stingiest in the NFL in allowing both points and yards, although its puny 15 takeaways should call for an asterisk."
