Given a good, or even decent, defense a keeper can keep the 3 or 4 shots on goal out. Given a defense that constantly allows shots on goal or offense to break the into the keepers box the keeper will always look bad. A keeper can only do so much. They are one of the ELEVEN players on a team, on the field at a time.
Everyone wants, or expects, the keeper to be a miracle worker. “COME OUT” is screamed by a coach and players alike as if the person did not just clear 10 other people to get to goal. “COME OUT” does nothing but make a keeper second guess everything they have learned (cutting off angles, coming out and getting big to block an opponent, keeper position in relation to where the ball is on the field, etc.). Instead of blaming the keeper for allowing in a goal, it might be a better use of time to take a look at the other 10 people on the field and ask what they could have done, should have done, to stop the person from getting to the goal in the first place.
