Backscreen,
I totally agree with you on that last post.
I know coaches don't like it, but I will "coach" my son when it will improve his game. It amazes me some of the basics that these "professional" coaches don't work on, particularly set pieces (which would only take 5 minutes of 1 practice).
I will say that I did tell my son he was allowed to direct the f-bomb at a few specific players during indoor because of the way those players treated every one (from yelling at them, to deliberately fouling--slide tackles from behind when the got beat and headlocks when they were up against the wall, to never rotating off while everyone else did) all while the coach sat there at midfield with his phone to his ear. Of course, I knew my son wouldn't do it, but it made him feel better that I was ok with him doing something to the "bullies".
