Football has a lot of numbers associated with it so I'd guess it's pretty fair, especially since Moneyball was published. (Assuming football coaches learned from it; I don't actually follow football.) I was actually more interested in your other example of entertainment industry executives.

I am pro-analytics: I think you should measure all the things you can because the numbers can be interesting. But just as you wouldn't judge programmers by lines of code, raw numbers about hiring are only a suggestive data point. To figure out if there's a real issue, we would need to go deeper and look for other things to measure. (But obviously we're not going to do that here in a chat room discussion.)
