https://www.reddit.com/r/nfl/comments/6 ... lation_to/Comparing pressure rate with time to throw. The model is that lower time to throw mitigates pressure by getting the ball out before the rush can affect the QB. Thus, the ratio between time to throw and pressure rate ranking should be close to 1.0. This guy compiled the stats from the 2016 regular season and another guy made a graph of them.

https://imgur.com/a/MjDMoI've circled Russ in blue, Tom Brady in red, and Rodgers in green. We can see that Brady's quick release relative to his peers mitigates the pressure he faces, again relative to the other QBs in the league, about exactly as expected. Rodgers holds the ball longer and experiences much less pressure than one would expect, so he's below the trendline. Russ holds the ball barely longer than Brady and experiences pressure at a much higher rate, relatively. So this whole "blame Wilson, Brady and Aaron get the ball out quicker even if their OL are worse, why can't Russ do that?" argument doesn't properly account for RW's circumstances.

Sorry, but this entire analysis is bogus, because it is based on doing arithmetic on ranks, which is nonsensical. Arithmetic requires real numbers, and ranks are not real numbers. Ranks are just orders; this comes before that,

but you don't know by how much. Ranks don't have a zero, and the arithmetic operation of division requires numbers that have a true zero. Division is not defined unless they do. Arithmetic also requires equal intervals, and ranks do not have them.

Addition and subtraction are defined for numbers on equal interval scales, but multiplication and division are not defined, such as temperature on the Fahrenheit scale. So it is nonsense to divide two Fahrenheit temperatures; 100 degrees is not twice as hot as fifty degrees, and we all get that from our experience.

Multiplication and division are defined for numbers on equal interval scales with a true zero point, such as temperature on the Kelvin scale. 100 degrees Kelvin is twice as hot as 50 degrees Kelvin.

Time is a properly scaled variable. Time ranges from zero to infinity, and each second is the same size as another, so arithmetic is defined for time.

Bottom line: don't even think about doing arithmetic with ranks. Use time instead.
