The 2012 season started so well for Mark Sanchez. With a comfortable 48-28 victory over the Buffalo Bills in Week 1, all the problems of the preseason and 2011 seemed to vanish. But that performance was due as much to an impotent Bills pass rush (which pressured him on just 6 of 27 drop backs), as anything else. Now four games into the season, Sanchez's completion percentage has plummeted to a Tim Tebow-esque 49.2 percent.
