Reply to comment by JPAnalyst in [OC] Correlation between heigh and performance of NFL Quarterbacks in 2022 by Exiled_From_Twitter

Yup, I appreciated your post. It was very interesting and I recognized that you were not trying to prove performance but rather something that I thought would have been more positively correlated (as you explained already haha). I definitely would have guessed that shorter QB's would have had a higher percentage of balls batted down (and very glad you used percentages). I then saw the two that were linked above and was like wow, these are pointless.

If I added a bit more context or lengthened the time period a bit it would have likely had a negative correlation b/c Russ and Kyler had poor seasons by their standards (the two main short guys) AND I could have gone back far enough to add Brees which would have really given the short guys a boost. But it didn't matter, pretty clear that of all NFL QB's, which is a selected and managed group, there's no correlation between performance and height.

Not only are they pointless. The OP just doubles down when you try to explain why they aren’t looking at things the right way. And they clearly don’t understand the game of football. I’ve had some frustrating conversations with them on my post.

And I agree, both of our analyses are impacted by survivorship bias. If you get to this point, you’re the best in the world. But within that context it’s still worth proving that height doesn’t make much (or any) difference. A slight build might make a difference in injury risk, but that’s a story for another day.
