A non-directed kick is what you are going to get though if everyone pushes up (other than on a fast distribution before the other side is ready) because everyone is going to be marked and everyone is going to bunched near the center circle.I'm not suggesting to just boot the ball. I'm suggesting kids shouldn't be held hostage to one style of play, particularly a pure possession style. No one plays full tiki-taka anymore because its no longer is effective. Teams figured it out. Also a strict possession style seems to go hand in hand with joysticking. Focusing on one style of play is one of the reasons kids don't develop soccer IQ. There is a time and place for possession and there is a time and place to send the long ball.
A blasted, non-directed keeper punt or goal kick drives me as crazy as a negative pass to preserve possession when you could send a high percentage long ball to your wing in space.
I will add that most people who complain about "boot ball", are the ones whose kids team lost to a team that played more direct.
The tension is that unless the coach removes the option, teams will tend to revert back to a non-directed kick just to relieve the pressure (since everyone gets punished by shame or getting yelled at for a goal against and people will always choose pain avoidance over a lower reward such as the off chance of starting a breakaway).
I'll share a story. My kid was on a letter league team where he split time with another GK. The other goalkeeper could not play with his feet. The few times he tried to play high and in support of the back he caused a couple disasters so he had a tendency to sit on the line, boot the ball on goalkicks and put the team into a defensive low block. My son was trained in the sweeper keeper style and is constantly playing high which pushes the CBS out of any sort of position to low block. Oil and water. The coach's preference was to play in my son's style. However, mid season the club lost it's center backs and had to put the alternates into first string. The alternates had a very hard time playing the coach's style and would constantly lose the ball leading to a counter attack. The coach was confident that they would get there, but the parents rebelled and demanded to know why he wasn't playing the game safer. The players also preferred the other goalkeeper because it meant they didn't have to take responsibility (I swear my kid's Latino league cbs at least want the ball) because the parents would go off on them if they gave up the ball. Got so bad the parents approached the coach demanding he play the other GK because it just leads to fewer chances against. It didn't wind up turning around the team's fortunes, but they did give up fewer goals against.
