The process for video review and the potential to expand the coach's challenge rule are again topics of discussion at the annual March meetings of the NHL general managers that began Monday and runs through Wednesday.

It was among the topics talked about in small group breakout sessions Monday and will be brought to the entire group of general managers and League executives here Tuesday for further discussion.

"We talk about that every meeting," said Colin Campbell, the NHL's senior executive vice president of hockey operations. "I talked to the NFL at one point at the outdoor games in Jersey and their challenge is like ours and all sports, where do we go in trying to make our game perfect with video review and how long does it take to make those reviews?"

Campbell said the discussion Monday included a conversation about allowing coaches to challenge plays involving pucks shot over the glass from the defensive zone that should or should not result in a delay of game penalty.

I think I can get behind just keeping the OT format the way it is.  We've seen the evolution of how overtime is played, and it's been interesting to watch these last few years since 3 vs. 3 was introduced.  The first few years, most of the goals were scored on the second possession's breakout, within 45 seconds of OT starting.  Now, there's more gamesmanship going into it and calculated decisions being made.  I like that.  

Adding possession rules with a cross-over line is a good way to make the game unnecessarily complex where you are just going back to having breakout after breakout.  

What I HAVE NOT liked with the OT format is the one game against the Wings where the other team (Ottawa, maybe?) possessed the puck for like two and a half minutes and just waited until they got the best possible looks to shoot.  That was annoying, and I fear that's going to be a trend in the future.  Without putting a sort of shot-clock in place, that's tough to prevent simply because there is so much open ice to defend with three guys.  I hope that style doesn't become more used, and hopefully it was just an anomaly because the Wings were doing so poorly at defending that night.

If the goal is to reduce shootouts why not make 3-on-3 OT longer?

If 70 percent of games end within 5 minutes of 3-on-3, that suggests that about 91 percent would conclude inside of 10 minutes, 97 percent inside 15, and 99.2 percent inside 20.

Personally I'd love 20 minute 3-on-3, and if nobody scores it's a tie. No more shootouts and in the whole league you might have 0-5 ties per year. 

Also: get rid of the offside challenge.

Offsides exists to prevent teams from either cherry picking or using the whole ice keep possession and slow the game down. Linesmen do their best to call it accurately but it's unreasonable to expect perfection when guys are skating in at 20 mph across a 85-foot-wide line at the same time as a 3-inch puck. 

I feel like if a linesman is doing his job correctly, anything that looks like a tie or too close to call, don't blow the whistle. Give the benefit of the doubt to the attacking team and let the players play. 

If it's that close anyway, than the spirit of the rule has been upheld. No one is getting a critical advantage from being an inch offside.
