This section, along with the section on defensive techniques, could also be titled How To Keep The Ball Out Of Your Net. The Keeper, Goalie, or Goalkeeper, as the one player who is allowed to use his hands is frequently called, is usually the last line of defense between the opposing team and their own net. They, along with the center fullbacks, usually lead the defense with their ability to see more of the defensive field and visualize opposing attacking plays as they develop. The Keeper is typically the most vocal player on the team out of sheer necessity, yelling to defenders where to line up, both on opposing free kicks, corner kicks, and in the general run of play. Experience is more important for the Goalkeeper than any other player on the team. Some techniques, like knowing exactly where to position yourself for various types of free kicks and when to come out after the ball and when to stay at home, are learned primarily through experience and being able to gauge one's own speed and ability as well as those of your teammates and opponent. Several techniques contribute to an effective defense of the net, with Narrowing the Angle probably the most important one for making the transition from a beginning Goalie to an effective Keeper.
