NHL general managers discussed diving and embellishment, the potential for more video review including goaltender interference and emergency-goaltender protocol on the first day of their annual March meeting.

The big topic of three-on-three overtime will wait until Tuesday.

GMs didn’t make any decisions Monday, instead breaking up into three groups to talk about some of the issues that most fans see as small but are important to those in the game.

NHL senior vice president Colin Campbell said there was lengthy discussion on Monday about crease presence. It comes down to how much should be allowed.

"We don't want to go near 'toe in the crease.' We don't want to go near that again," Campbell said. "But we want to be able to instruct the referees. We want these guys to tell us what is crease presence. When should a play be called off, i.e. that's a goaltender who plays like (Henrik) Lundqvist. He hugs the goal line. Maybe there's another goaltender who plays atop the crease. Does that matter if the goalie leaves you room? So we talked about crease presence. These things seem anal until you get into Game 6 and 7 in the playoffs. They're not anal anymore. They're important."

A potential coach's challenge was brought up again.

"If we introduce coach's challenge, should we expand it to pucks over the glass?" Campbell said. "It's a difficult one to assess from our vantage point in Toronto. But do you guys want us to help the officials in that case? We would never add a penalty. We would only take one down."
