and all those stats can be worthless
1. total passes and % passes completed-a 100+ passes with 95+ completion rate are worthless if they result in nothing(as seen many times in Barca games this season,especially in the two games against Bayern)
2.movements,with directions-you talking about all the movement from one player in a game,because I doubt I have ever seen that or that it can even be displayed,there would be like a million lines showing a players movement and therefore very messy and unreadable
3.no of passes leading to a goal assist-I dot really get what you are trying to say here?
4.KM ran-players can run a lot and for nothing,but others can run less and do 10 times more with the amounts of KM they ran(all down to clever positioning,anticipation etc)
for example I would say Pedro runs a lot more than Busquets but steals the ball a lot less and his defensive contribution is a lot less significant(of course Pedro is on the wing and that makes a big difference but just trying to show you what I meant)
they can be very useful, and it totally depends what information you are digging out of them. All what you wrote was based on assumption that 'stats can be useless'-quoting such examples.
1. it does shows a player's ability to pass. (further breakdown can show 5 % of those were long passes with 50% of completion rate, you certainly know, this player can't put up a long pass. e.g)
2. Movements maps are very useful, as you can analysis if a player is moving into right places to recieve a pass (for example)
3. That could show if a player has a vision to create effective plays,(making a great through ball for a player, who made the assit)- this he the player actually put another player in great position to make an assist. (wonder why sergi busquets is so important ?) he is the one who make intelligent passes, analysis the situations and starting the attack from behind.
4. (again, it can, but this is a great example you quoted yourself. The stats can exactly show such information-useful to me, if i can know, who is running useless and who is making effective runs)
In pedro vs busquets example you are comparing oranges with apples.
