Stats are for fans that don't understand football and need numbers to tell them how good we are.
I agree that some stats don't really tell you a lot about a player - pass completion percentage, tackles made etc in isolation don't tell you a lot about a performance and can mislead people who don't understand the game.
Not sure if you've read the article mate, but I actually think the reverse is true on this article. It gives legitimacy to a lot of points that people who do understand football have been saying for years, but had no stats to back them up.
The most obvious one being David Silva being top of the "sequences" that lead to a shot. As an earlier poster said, anyone who's watched Silva play and understood his game knows that his involvement in dictating play and helping to create chances is his key attribute.
Simply looking at his goals / assists stats won't tell you that. That's why people that don't understand the game will say "Silva's not that good, look at his stats compared to Ozil" / Hazard / whoever is flavour of the month.
Another thing the article shows is team play. So it shows Liverpool play a lot of passes, and at a very high tempo. Or Klopp's "heavy metal" football. Anyone who's watched Klopp's teams play and understands them, will tell you that's how they play.
Similarly Leicester are one of the fastest teams, and also play the fewest passes. The archetypal counter attacking team. Again, if you understand football you'd know that's how Leicester play.
I'm not a huge stats fan, but I actually think the content of the article applies data in a way that is useful and informative. Stats are only going to become more and more prevalent in football, so at least this is a way of making it insightful.
