Rating QBs by defensive performance

I heard about this analysis related to Cutler's performance. How good is a QB when you look at the defense that he played with? On this board, we often talk about "if only the D held a team under 30", Brees would win almost every game. Is it really true?

Check out this interesting analysis on Pro Football Reference.

The good news for Saints fans -- Brees is one of the better QBs in the modern era when looking at his win/loss percentage and comparing it to his defense's ability.

The bad news -- the analysis lists Archie as the worst QB of all time.

Let the discussion begin.
