NHL Coaches should challenge goals under the NHL's video review system, according to Jon Cooper of the Tampa Bay Lightning.

I'm a believer — and I don't know if I'm in the minority on this — but I  don't think that should be in our hands," Cooper said

after Tampa Bay cut the Colorado Avalanche's series lead to 2-1 with a 6-2 win in Game 3 of the Stanley Cup Final.

I just don't understand why I have to choose between onside and offside when the stakes are this high. On Monday night

the Lightning successfully challenged Colorado winger Valeri Nichushkin's first-period goal. After video replays

revealed that Avalanche defenseman Bowen Byram pushed the puck outside the attacking zone and then back over

the blue line, leading it to be offside, the goal was overruled. The Lightning bench did not immediately signal for a coach's

challenge, and there was a large lag as they viewed the game from various perspectives. Colorado coach Jared Bednar

stated, "It was probably three times the length we normally receive." The fact that the delay occurred after the goal

was "sort of rough," according to Avalanche winger Mikko Rantanen. I don't  think the can drop the puck if nobody is there," remarked  Rantanen.
