Click here for the rest of the article, showing the best QBs of all time, and the single season leader each year since the merger.Before the 2006 season, I wrote about the best quarterbacks of all time. With some more data on my hands, I decided to update that post. On Friday I discussed the methodology used, and yesterday, I ranked the worst quarterbacks in league history.
A couple of reminders. One, I ignored all post-season data, at least for now, mostly because it’s a complicated issue that’s worth separating out for a day. Later on this week, I plan to revisit post-season data. Two, on the list of the greatest QBs ever, I’m including sack data, and rushing yards, and using the league average as my baseline. Occasionally, though, I’ll use some other requirements when the rankings change substantially as a result.
What was the greatest season in QB history? It’s been almost a quarter-century, but Dan Marino’s 1984 season still stands alone. Sure, Marino averaged 8.51 adjusted yards per pass and 8.11 adjusted <em>net</em> yards per pass, but a few other QBs have topped that. What makes Marino's season so amazing was that he kept that pace up for over 564 passes, in an era where the league average QB threw for just 4.61 adjusted net yards per attempt.
Peyton Manning and Tom Brady don’t come far behind, with their 2004 and 2007 seasons ranking second and third, respectively. Right behind those years is Otto Graham’s 1953 season, an oft forgotten yet incredible season. Graham averaged 9.41 AY/A while the rest of the NFL averaged only 3.40 adjusted yards per attempt. The table below shows the top 50 seasons by all QBs in NFL history.
