Baltimore’s Joe Flacco wins Week 13 with a 58.05-point game (at Miami’s expense) in the Miami Herald’s Passer Success System (PASS) NFL quarterback rankings, leaping from 15th to ninth in the the season standings. Drew Brees maintains a comfortable overall lead, with the playing field level now that byes are done. The Dolphins’ Ryan Tannehill barely stays in the chart, dropping two spots to 20th. Our cumulative rankings use a simple formula unchanged since their inception in 1998, factoring accuracy, yardage, TD/interception ratio and team result. Most rating systems including the NFL’s and ESPN’s are complicated and percentile-based, allowing players who miss half a season to still win a season title. These rankings place a premium on consistently productive QBs who who avoid injury or benching. Watch for our updated Top 20 chart in this space each Sunday.
