The spacing was horrible, and I don't know why. Too much dribbling, not enough moving without the ball.
So much of what is wrong with this team is attributable to their inexperience, and in particular their lack of recognition - they dribble when they should pass, pass when they should dribble, shoot when they should pass, pass when they should shoot, etc., etc. That's just the half of it. It's going to take a ton of games for them to get where they need to be and there is no short-cut to getting there.
