I am a football coach, and while this article seems logical. I believe there are too many variables, like stock trading. And even if you could write a program to identify all useful variables, coaches will often evaluate themselves for tendencies, and call plays/defenses to go against their tendencies. I have used breakdown software and it is good, but the sample size it often too small. Two or three games is not nearly enough plays/situations to analyze it using algorithms. So, some might say, by the time the post-season comes along, the sample size would be big enough, but that is also not the case. Only the last few games are relevant when breaking down games. By the end of the season, early season games are useless. Also, the team you are playing might not have played a team with a similar sceme to yours, so you have zero sample plays that are useful to you.
