My perspective as a referee:
Possession only works when your players are better than the other players. One wrong touch and the other team is on the attack and has advantage. When wins matter, all teams fall back on a direct style looking to feed their best athletes as quick as they can. A direct style is often confused with kick ball. In a direct style, players are attempting to purposefully cover distances with long balls. While there are many lower percentage long pass, its different that kick it hard and as far as it can go. Weaker teams facing possession team will always counter with a direct style, with weaker players falling back on kick-ball.
At the 7v7 and 9v9 stage - winning clubs do not play possession soccer. They play a direct style that is intended to boot it up the field to their skilled/fast studs/studdettes. Almost every 7v7 team has that "1 player" that can dominate. The teams that tend to win a lot of games have 3 or more of those dominant players.
At the younger 11v11 the dominant player has much more ground to cover and becomes easier to neutralize. We start to see possession style as a means to break down defenses until a direct opportunity presents itself.
At the older 11v11 levels, most teams are now attempting to play possession until they get behind and then its all bets are off and direct style to get some points.
