Following the disaster that was the officiating in the 2019 playoffs, the NHL has expanded their challenge system to include a third category beyond goalie interference and offside.
Coach’s Challenge of goal calls on the ice that follow plays in the Offensive Zone that should have resulted in a play stoppage, but did not. This change will allow Challenges of plays that may involve pucks that hit the spectator netting, pucks that are high-sticked to a teammate in the offensive zone, pucks that have gone out of play but are subsequently touched in the offensive zone and hand passes that precede without a play stoppage and ultimately conclude in the scoring of a goal. -NHL Public Relations
The addition of the new challenge also changed the rules on the penalty for incorrect challenges. Previously, a failed goalie interference challenge would result in the loss of a timeout and a failed offside challenge would result in a 2-minute delay of game penalty.
Now, all three challenges are subject to the minor penalty if they are unsuccessful. Thus, timeouts now return to being just timeouts, and teams are never ineligible to challenge a play. However, the penalty gets stiffer with multiple failed challenges.
Teams will be permitted to exercise a Coach’s Challenge at any time, but with escalating “consequences” for unsuccessful Challenges. The consequences of unsuccessful Coach’s Challenges will be made consistent across all three Categories of Coach’s Challenges: (1) minor penalty for Delaying the Game on a Club’s first unsuccessful Coach’s Challenge; and (2) double minor penalty for Delaying the Game for each additional Coach’s Challenge that is unsuccessful. -NHL Public Relations
That brings us to the Golden Knights, who do not exactly have a sterling record challenging goals.
Gerard Gallant has initiated 24 goalie interference challenges as head coach of the Golden Knights. He’s been successful in just three. He went 2 for 13 last year and 1 for 11 in 2017-18.
