GMs want 3-on-3 OT format A proposal to change the format of NHL games by instituting three-on-three play in overtime has gotten the support of the league's general managers, although final approval is still needed. The GMs devised two options related to overtime: a switch to three-on-three play for five minutes that the Swedish Hockey League uses, or a four-on-four to three-on-three approach similar to the lower-tier American Hockey League. The recommendations will go to the joint NHL/NHL Players' Association competition committee, which meets in June and must approve any rule changes. That committee also will consider the other recommendation from general managers of instituting a coach's challenge system for goaltender interference. If it goes through, coaches will be able to challenge goalie interference only on goals scored and only if they have their timeout left. While the NHL understands shootouts are popular with fans, the league would like more games going beyond regulation to be decided in overtime. — Agencies
