Donovan McNabb struggles on third down

Washington Redskins quarterback Donovan McNabb was yanked from Sunday's game for a variety of reasons, according to a coaching staff that's having a hard time getting its story straight. ESPN analyst Trent Dilfer pointed to McNabb's performance on third down ("critical situations") as a reason why coach Mike Shanahan might have lost faith in his quarterback.

NFC West blogger Mike Sando spent a portion of his offseason discussing McNabb as a possibility for the San Francisco 49ers. He's now gone back and compared current and former NFC West quarterbacks to McNabb on third down through the first eight weeks of the season.
