It would be only for a challenge of offside, and the coach would not have to be in possession of his timeout in order to challenge. There is no recommendation to change the rule for a coach's challenge of goalie interference.
The hope from the GMs' perspective is the potential of a minor penalty would reduce the times a coach uses his challenge to initiate a review for offside. There were 131 offside challenges this season, a 32 percent increase from last season.
"We got a little bit of flavor from the Competition Committee that they don't like the offside challenge, so we're trying to do something about it," NHL senior vice president of hockey operations Colin Campbell said. "The players don't like the offside like the fans and media. So we're trying to temper it a little bit and take care of the obvious offsides, but the close ones, hopefully this will eliminate [the challenge]."
Campbell said 30 of the 31 NHL general managers supported the recommendation. The support is largely because the GMs feel the change would bring the offside challenge closer to its original intent, which was to correct a goal scored after the attacking team obviously gained the zone illegally.
As it is now, a coach, largely through the help of video coaches who are not on the bench, are challenging for offside when they think a skate blade might have been off the ice.
