Same with football.... from what I understand it’s not predominantly what you do with the ball that scouts look for. It’s positional sense, awareness, communication, decision making, work ethic.... plus many other things. Obvs that raw talent has to be there somewhere but players who can naturally do the things without the bell catch your eye at times. Think it was Bobby Robson who said the only thing separating a top amateur from a pro was the ability to always choose the right option...decision making.
Or in the case of acadamies for absolutely years: are you 2ft taller than everyone else your age.
