Annus Horribilus Quarterbackus

Dr. X posts this from the NFL Institute for Non-Parametric Evaluation of Quarterback Performance:

"Here is a list of quarterbacks who are 1) still in their starting job and 2) are above the NFL IAYPA average of 5.4 yards:

"Peyton Manning (7.2)
"Drew Brees (7.1)
"Carson Palmer (7.0)
"Philip Rivers (6.4)
"Marc Bulger (6.4)
"Tom Brady (5.6)

"That's it. I doubt if there's ever been a year where more quarterbacks got knocked out of their jobs. McNabb (7.4) was leading before he got knocked out. Romo (7.2) is off to a white-hot start, and already has a lot of attempts."
