Brian leads a nice discussion here on models, probability and uncertainty. But I still think it misses a big point Shanahan is making. And the Jags decision to attempt a late 60-yard FG last Sunday, down 3, is a great example.
The models said go for it, but those models assumed a league-average kicker makes the kick roughly 40% of the time. But Cam Little is not average and his coach knows that. If I were the coach, what I’d want to know is, “what % would Cam need to make the FG to flip the decision from “go for it” to “kick”? If it’s 55%-60%, I’m kicking!
That, to my ear, is what Shanahan is getting at when he says 51/49 is not necessarily persuasive.
I’d like more analysis like this from the football quants. Some recs (go for 2 late in the game down 8) have no context factors which can switch the recommendation, but a lot of 51/49s do.
With all the talk about Kyle Shanahan's 51% comment, I want to take some time to walk through why a lot of the discussion yesterday was off the mark. I'm going to focus on just one of the points made--uncertainty. Thread:
