As with many leagues at youth and amateur level, it can be evident before a ball is kicked the most likely outcome is a high scoring win for a particular side.
This player/coach has went into the game knowing that and sent out her team to win, but once the game was in the bag, to sit off and allow the opposition to have time on the ball and build confidence. Thus making it a better spectacle for the supporter and both sets of players gaining something from the exercise.
Now we've talked about teams playing fringe players, trying players out of position and playing keep ball, to avoid running up high scores. But is this a tact that youth coaches with a true ethos towards development should be looking at?
