The National Hockey League is always looking for ways to improve its accuracy rate when it comes to ruling on controversial goals.
NHL Hockey Operations is expected to meet with a group in the near future that has designed a camera system that can be installed in the posts of the nets. This system may provide a more clear view of the goal line and by design may assist the league in determining - conclusively - whether or not the puck crosses the line.
This meeting was planned well before Tuesday night's game between the Philadelphia Flyers and Ottawa Senators where midway through the third period, it appeared Ottawa's Kyle Turris had given his team a 3-2 edge. Turris' shot ricocheted off both of Nicklas Grossmann's skates and from the camera angles provided, it seemingly crossed the goal line.
Veteran referee Paul Devorski immediately waved off the goal and a lengthy video review was unable to warrant overturning the call on the ice.

The NHL is very sensitive to this issue and would love to find the technology that can deliver 100 per cent accuracy. That's unlikely to happen anytime soon, so Hockey Operations does its best to deliver consistency.
The league also installs additional 'in-net' cameras after the warm-up of each game which aren't always used for television purposes, mostly because of quality. However, they do assist the video review process by offering another angle when televisions robotic cameras aren't available.
The league has explored other methods of improving its odds of getting it right. Most recently, a green line inside the net and below the goal line was tested as part of a research and development strategy in 2011. If a puck at any point touched the "verification line," by design, it would be ruled a good goal as it would have had to completely cross the goal line.
At the time, it seemed like a great idea. But the depth of the ice over top of the goal line and verification line impacted perception to the point that the NHL abandoned the experiment.
The Cyclops and Hawk-Eye systems used in tennis were also investigated by the National Hockey League. But for a variety of reasons, including the expense, the NHL decided this technology wasn't a fit.
Sensors in pucks, cameras in goal posts, computer generated tracking software are all options that have either been considered, or are, being looked at. But there doesn't appear to be a visual aid or device that has been developed that is worth the cost and can guarantee perfection.
Until that happens, it's 'old school' for the NHL.
