Wrap-up: Steelers 32, Cardinals 20

Thoughts on the Pittsburgh Steelers' 32-20 win at the Arizona Cardinals:

What it means: Pittsburgh delivers its most convincing win on the road this season. Unlike like last week, the Steelers came to play in the second half and finished off the Cardinals. Pittsburgh becomes the first team in the AFC to reach five wins, improving to 5-2.

Thumbs up: Steelers quarterback Ben Roethlisberger. When the Cardinals cut the lead to 17-14, Roethlisberger responded by completing 6 of 7 passes for 80 yards. He finished off the drive by eluding an unblocked defender and throwing a 4-yard touchdown. Roethlisberger finished 25-of-38 for 340 yards and three touchdowns.

Off to the races: It's getting kind of funny when defenses don't double Mike Wallace on every play. He reminded everyone again about that point when he scored a 95-yard touchdown in the second quarter. It's the longest pass in the Steelers' storied history.

Pick-ing it up: The Steelers, who had the fewest forced turnovers in the NFL, picked off Kevin Kolb in the first quarter. It led to the Steelers' first touchdown, a 12-yard touchdown pass to Heath Miller.

What's next: The Steelers face their biggest challenge at home this year when they play the New England Patriots, who are coming off a bye.
