The coach's challenge is getting good reviews from NHL general managers in its first year of use, but it's not exempt from a little tweaking.

Discussion of the coach's challenge headlined the first day of the NHL general managers meetings Monday, and support was strong amongst the 30 GMs, who see the added opportunity to get a goal call right as beneficial for the game.

The initiative allows coaches to use video review to dispute goals scored on potential offside or goalie-interference plays.

"I think everybody feels fairly comfortable with it," said Maple Leafs general manager Lou Lamoriello. "The whole objective is to get it right."

Still, the NHL will make one tweak for the playoffs, adding blue-line cameras to the arenas of the 16 post-season teams. The cameras are intended to further aid clubs in determining whether to challenge a goal on account of offsides.

"I think it was a good day to show where we're at with the coach's challenge and where we can get to," said Colin Campbell, the NHL's executive vice president and director of hockey operations.

Forty-two of the 69 challenges (61 per cent) for offsides were upheld entering play on Monday night with 27 overturned to "no-goal."
