It's also great in baseball because there are sooooooo many leagues, soooooo many players. You can't watch them all. You can look at numbers, and pull out a top 50 prospect list of guys you like, and then from there watch tape. Still always comes down to tape.
Football there are things you can analyze - whether you should go for 2 in x situation, win probabilities etc. But you can't really use it for accurate player evaluation. So many positions literally have no stats at the end of a game. I assume coaches see on film when a run goes for no yards, who is at fault. I don't need a computer to tell me that.
