This page lists offensive stats for quarterbacks for five different pass categories: left, middle, and right as well as short and deep. Short passes are defined as passes going up to 15 yards through the air; deep passes go 16 or more yards through the air. All directions are listed from the offensive perspective.
DYAR represents total value. DVOA represents value per play. These are individual passing DVOA ratings, not team passing DVOA ratings. Numbers are adjusted based on the opposing defenses and include defensive pass interference.
Why are these numbers all so positive? DVOA averages for passes are well above 0.0% because passing DVOA also includes sacks, which are all negative and not considered in the stats listed here. Also, deep DVOA tends to be very positive because any deep complete pass gains at least 16 yards by definition!
Numbers in red represent NFL averages for the season. These averages are done by team, not by quarterback, so DYAR and pass totals are league totals divided by 32.
