I looked into it at one point this off-season, and roughly 72% of the variation in win percentages for QBs across the league could be explained by their QBR. That's pretty damn good. For reference, passer rating could explain 52% of win percentage variations. So, it does a better job of identifying QBs that are valuable to their team than passer rating does.
I like the QBR tries to incorporate QB rushes, sacks, and fumbles but it just doesn't work
The best QB does not always win. So you should not measure QB play by who wins. For example, a QB on a good running team will have more manageable third downs to convert and QBs on the best overall teams will have more comeback wins.
The best QB does not always win. So QB rating should not be judged on how it correlates with winning.
