The two biggest jumps in passer rating since 1980 have been recorded by current NFC South starting quarterbacks.
New Orleans quarterback Drew Brees set the season-over-season record back when he was with San Diego, making a 37.3 point improvement from 2003 to 2004. But Tampa Bay’s Josh Freeman almost matched him last season. Freeman improved his passer rating by 36.1 points.
