Statistics in sport

I was at one of my club Netball training sessions earlier this week and was asked to take statistics for the match play during selections. Without thinking too much about I took the statistics on an iPad using a special netball app.

Later on that night I got to thinking about the app and the use of statistics in sport.
This app was able to tally almost everything a player did right or wrong on the court. Whether they got an intercept or threw a bad pass. It could all be documented. But how accurate is this? Do we count a 'tip' of the ball as a positive? Despite the ball still reaching the desired target, hence the tip has no effect?
And what about the work what is done 'off the ball'? There is never any solid evidence for this. It is only what a coach or spectator observes and how they perceive the work being done.
While the use of statistics has its benefits in sport it is vital that all aspects of a players game are taken into consideration. Also, combinations of players are important. A game of netball (for example) would not work if you had 7 individuals on the court. Instead you need a team. While individual talent is needed, a team doesn't work without combinations and a solid understanding of the players around you.
Statistics are one aspect or perspective of sport. And while they are valuable, they are not the be all and end all.
