See this is the major flaw in basing anything in football solely on a stats model. You have to see with your own eyes, I am not saying stats can't be helpful but why only use this or why use this as the first port of call when deciding on a player.
The first bold bit, what if the strikers were not that good. What if 85% of balls were perfectly placed but the striker was not in position or they were well marked. Maybe over time (a long time) you can judge but the modern manager doesn't always have time to assess a player over a long period of time.
The second part, who said this was a fact? A top attacking player does not only have to be a player who has a ton of shots. A top attacker could be somebody who simply poaches on the odd chance and has other elements to their game which bring other players into play, somebody who drifts out wide creating space for others, is an example. Barrow have a striker that is absolutely superb for us, with the way we play (or played as he is injured), I would dare say that he doesn't have an average anywhere near that so to be so simple as to have a basic stat and say they are not good enough is not the the right way to go about things.
For me, a scout needs to see a player before judging, how they interact with teammates, what kind of style is their current team playing, how adaptable do they seem, etc. The idea of basing a scouting strategy on seeing players play is not perfect but it is 100% logical. Pienaar is a good example, I don't know the stats but it is possible that he passed to Baines for an assist more than he assisted himself but he was massively instrumental to how we played. Now if somebody just looked at his stats as a midfielder then they would pass when in reality, if they watched him they might think that he would fit into the way they play.
Simply put there are no perfect ways to judge a player but watching them actually play is still the best method, stats can easily be used to back up certain aspects but seriously who gets into the scouting business to sit in front of a PC looking at numbers, you want to be out there watching football, watching players, judging with your own eyes.
Back on topic....Kopites are...... well we all know the rest.
