They probably didn't have enough pitches to get longer games for all the times (or it'd stretch out over days). Still, 13 is a strange number.
Been playing some smaller tournaments here too. I'm not a great football player by any means but did pretty well by virtue of decent team play. Let the good players do the attacking work, and have the lesser players stick to their positions/defensive work while running into gaps once every while. Most of the teams that play in these tournaments are a collection of selfish football players, where everyone thinks they're a great player. No one wants to defend. So they lose.
