Why do people so obviously feel threatened by statistics?
Seriously, the emotional nature of the responses, from the very beginning, seems to me to be an entirely inappropriate reaction. This isn't the first time I've seen people who don't like stats respond aggressively to the very suggestion that there could be some wisdom gained by their study.
Seems to me that people's problem with statistics stems from a strange misconception that ceding any value to statistics means surrendering the entirety of your judgment to a statistical model. Nothing could be further from the case.
Any statistician worth his salt is entirely aware of just how limited any statistical model is. It is limited by the integrity and comprehensiveness of the data, and care needs to be taken about the assumptions made when interpreting it. At their best, statistics in sports are meant as a TOOL to aid your judgment, not a substitute for it. Nobody is suggesting that stats can or should replace scouting or "watching the games."
But a lot of things happen in every game. The human mind can't possibly keep track of every play of every game of every weekend. A statistical model can. Thus, stats, when scrupulously interpreted, can provide insight that is often counter-intuitive, and, when synthesized with scouting analysis, can provide a more complete picture of the reality of football than either tactic can alone.
