After that controversial OT goal, should the NHL embrace goal-line technology?

Did the puck cross the line, or not?

That's what the hockey world is furiously debating after the Edmonton Oilers fell to the Anaheim Ducks in Game 4 with a controversial overtime loss Sunday night. Ryan Poehling scored 2:29 into overtime, and the Ducks pushed Connor McDavid and the Oilers to the brink of first-round elimination with a 4-3 victory.

But the issue — as observers, players and commentators are arguing — is that the puck under goaltender Tristan Jarry's skate was ruled a goal despite none of the on-ice officials having a clear sightline.

The call on the ice — that the goal was good — triggered an automatic review by the league. In order to overturn the call, the NHL situation room would have needed conclusive evidence that the puck didn't cross the goal line, according to Sportsnet. The call was confirmed, leaving Edmonton trailing the series with Anaheim 3-1.

The controversy has reignited the debate over whether the NHL should follow other leagues like Major League Baseball, which just starting using the Automated Ball-Strike (ABS) challenge system, and tennis, which uses electronic line calling, to embrace new tech when making calls.

"I just don't understand how, without someone behind the net, you can say that that's a good goal," NHL insider Elliotte Friedman said during a Sportsnet broadcast after the game.

"This is another call for some sort of tracking technology that can solve this problem for everybody."

A common thread in the debates about the call is that goal-line technology could have eliminated the need for a debate at all.

The NHL has used Sony’s Hawk-Eye technology for the past decade as part of Synchronized Multi-Angle Replay Technology (SMART) services in every team’s arena to make replay
