• Sanchez is currently the only qualified quarterback in the league to have a sub-50.0 completion percentage.
• A quarterback's Points Above Average figure measures the number of points contributed by a quarterback over the season, accounting for QBR and how much he plays, above the level of an average quarterback. A 50.0 Total QBR is the league average.
• So how badly is Sanchez performing? Since the start of the 2008 season, no quarterback has cost his team more net points than Sanchez, if replaced by a league-average quarterback. Sanchez has been worth minus-75.0 points to the Jets over the course of his career -- worse than JaMarcus Russell, Derek Anderson, Jimmy Clausen, et al.
• Sanchez has overthrown or underthrown 47 passes this season, or 26.6 percent of his total attempts -- the highest percentage of any qualified quarterback.
• Sanchez is completing only 47.6 percent of his passes thrown five yards or fewer downfield this season, easily the worst in the league. The next-lowest figure belongs to Josh Freeman, who has completed 58.6 percent of his short throws.
