I manage an under 15 team. We are one of the weaker teams and have lost good players because we lose a lot more than we win as we give all players good game time. However there comes a time when we will be uncompetitive if we keep losing our better lads.
So I am giving all players a similar number of matches but giving the better players between 60 to 80 minutes and the weaker ones 40 to 50. If the parents don’t like it tough. They can manage the team next season if they so wish.
