So, when the offense shoots don’t just try to block the shot. Attempt to keep the ball. Use soft hands so that every block is a turnover. Your job as a goalie is to protect the ball. If you gain control of every ball that enters your zone you’ll have a much better chance of winning.
By the same token, when you pass or shoot from the goalie zone - have a plan. There’s no point in just sending the ball to the other goalie so he can give it to his forward. (Sorry for the sexist pronouns).
A good calm goalie can help his teammate forward concentrate on his own job which is to control the ball up front, then score.
The goalies determine the game’s pace - so take control.
