IMO YPA is a good metric to use for quarterbacks. You can raise it by either completing a higher percentage of short passes or by hitting more deep passes, so it rewards both accuracy and aggressiveness.

31. Mason Rudolph 6.2

Bridgewater didn't throw enough passes to qualify per ESPN, but his 7.2 YPA would have been tied for 16th - tied with Baker Mayfield, just a hair below Matt Ryan, and right above Aaron Rodgers.
Anyway, the tl;dr of this is that Dak was one of the most effective QBs in the league on a per-play basis, Bridgewater was pretty decent, and 2019 Brady was absolute trash
