Actually, if you read the article, you'd see it was only on the 2005 playoff run,
He only broke down the playoffs.
I broke down the entire season. From my site:
heck out the pass:run ratio by quarter during the regular season:
First quarter: Pass: 50 - Run: 50
Second quarter: Pass: 53 - Run: 47
Third Quarter: Pass: 39 - Run: 61
Fourth Quarter: Pass: 36 - Run: 64
During '05, the Steelers played 20 games. In 11 of those games, they threw more than they ran in the first quarter. In six of those games, they ran more than they threw. In the other three, it was an even balance.
