TAMPA, Fla. -- The Arizona Cardinals and Steelers are both aggressive on defense.
Having watched Arizona, I know their defensive backs aren't afraid to take chances in trying to make plays on the ball. They've picked off lots of passes, particularly in the playoffs.
Aggressive teams can sometimes become vulnerable against a crafty quarterback, or a quarterback with the physical ability to extend a play as Ben Roethlisberger often does.
Santonio Holmes caught six passes for 128 yards and two touchdowns against the Cardinals last season. Arizona's Larry Fitzgerald caught 10 passes for 120 yards in the same game, which the Cardinals won, 21-14, at University of Phoenix Stadium.
