The coach's challenge faces a detailed review from the league's 30 GMs when they gather here early this week for their annual three-day meeting.

Rule 48 for hits to the head is also going to garner more conversation, as in whether it's time to further adjust the definition. And GMs should get their first official look, even if cursory, at potential expansion draft rules.

But I suspect the coach's challenge will be the hot-button issue. One of the main points of contention among some teams is that the rate of overturned calls is too low. According to numbers provided last week by the league, about only 21 percent of goalie-interference reviews have been overturned this season, while the numbers is around 39 percent for offside reviews. There's also frustration among some teams as to what exactly is goalie interference.

"I think we're going to review it, there's going to be discussion. Who's going to handle it? Will it stay the same way?'' said Dallas Stars GM Jim Nill. "This isn't new to us, we've had a lot of discussions about this before it came in. We knew where maybe it would end up.''
