Does defense win championships?
The question will be put to the test Sunday, in what is shaping up to be a classic Super Bowl matchup of high-scoring offense vs. an ultra-stingy defense.
Pittsburgh's top-ranked defense, having held both of its playoff opponents to an average of 244 total yards, squares off against the high-powered Cardinals offense that has recorded 357, 360, and 369 yards in three playoff games.
Thirteen teams have finished first in total offense in the regular season and reached the Super Bowl. Only seven of them won. Two of those seven also possessed the league's best defense.
Quarterback Kurt Warner has followed up a regular season in which he passed for the second-most yards (4,583) in the NFL with a stellar run in the postseason. Through three games he has 770 passing yards, eight touchdowns and two interceptions.
Said Fitzgerald: "We are looking forward to the test."
