Matt Ryan's raw numbers were ugly, but he also played a brutal schedule that included 13 games against teams that finished in the top half of the league in pass defense DVOA, and seven games against teams that finished in the top six. He got a boost of 300 DYAR after schedule adjustments; no other quarterback went up by even 200 DYAR. Ryan faced that slate with his top receiver out of the lineup for two-thirds of the season, and still made the top six in DYAR for the fourth straight season. He could be the most underrated quarterback in the league.
