This is true but also disingenuous – especially considering that in your article on Jay Cutler, one of the very things you cited was his Win-Loss record. Of course, the assumption is the QB is not SOLELY responsible for wins but I suspect that the very impulse for this data dump is that you, like most rational people, realize that QB performance is – over a large sample size – the biggest determinant of wins and losses. In head-to-head match-ups, there is a strong correlation between the QB with the higher passer rating – ceteris paribus – and win probability (and therefore wins).

It’s equally as disingenuous to say “wins are a TEAM statistic, but a QBs ‘individual’ stats are the sole purview of the QB.” TD%, Int%, passer rating, and so forth, are all widely regarded as ‘individual’ stats even though there must be an offensive line that must block, receivers must get open and catch, coaches must call adequate plays to exploit mismatches, and QBs, of course, must make correct audibles, reads, and throws.

I haven’t looked through your archive, but I think you wrote a bit showing a strong correlation between QB performance and Wins. Let’s not overthink this even though most reasonable people know that a great QB on a terrible team is ‘better’ than a mediocre QB on a great team.
