Warner standing tall among division's QBs

Posted by ESPN.com's Mike Sando

Two weeks ago, 49ers quarterback J.T. O'Sullivan was averaging 9.4 yards per attempt with a 104.6 passer rating.

My thought at the time was that O'Sullivan would never average that many yards per attempt, given that Tom Brady never averaged even 8 yards per attempt until last season. Yards per attempt is a telling indicator of health in the passing game. The stat is one variable used in calculating passer rating.

O'Sullivan's average has fallen to 7.8 yards per attempt, still a high number that could continue to decline as the 49ers face tougher defenses.

The chart ranks NFC West quarterbacks by yards per pass attempt. Matt Hasselbeck is on pace for eight touchdown passes and 16 interceptions.

Kurt Warner ranks fourth among NFL quarterbacks in yards per attempt. Drew Brees and Philip Rivers are at 8.6, followed by Tony Romo (8.4). Warner has previously averaged 9.9, 8.8, 8.7 and 8.2 yards per attempt in a season. His career average is 8.1. For reference, John Elway never averaged more than 7.9 in a season. His career average was 7.1.
