Goaltender Trapezoid
During the 2004-05 American Hockey League (AHL) season, an experimental rule was implemented for the first seven weeks of the season, instituting a goaltender trap zone, more commonly called the trapezoid in reference to its shape. Under the rule, it is prohibited for the goaltender to handle the puck anywhere behind the goal line that is not within the trapezoidal area. If he does so he is assessed a minor penalty for delay of game.
The motivation for the introduction of the trapezoid was to promote game flow and prolonged offensive attacks by making it more difficult for the goaltender to possess and clear the puck. The rule was aimed at reducing the effectiveness of goaltenders with good puck-handling abilities, most notably Martin Brodeur and Marty Turco.
The area consists of a centred, symmetrical trapezoid. The bases of the trapezoid are formed by the goal line and the end boards. The base on the goal line measures 18 feet (5.5 m) and the base on the end boards measures 28 feet (8.5 m).
The seven-week experiment proved so successful that the AHL moved to enforce the rule for the rest of the season, and then was approved by the NHL when play resumed for the 2005-06 season following the previous lockout. The ECHL, the only other developmental league in the Professional Hockey Players Association (along with the AHL) also approved the rule for 2005-06.
