World Cup of Hockey shows strengths & shortcomings of new hockey technology

“Whether it’s digitally enhanced dasher boards or puck and
player tracking, we’re ready to embrace new technology that isn’t a gimmick,”
NHL commissioner Gary Bettman said in an early assessment of the World Cup.

The technology in question, which includes referee cams and
tracking chips, has many potential benefits for coaches, broadcasters and fans.
For fans, body cameras that were worn by the officials provided a unique
perspective. The ref cams captured everything on the ice, including memorable
moments like Connor McDavid delivering a precision assist to Auston Matthews
and Alex Ovechkin screaming at a ref after his goal was disallowed.

Coaches, on the other hand, will probably find more value in
the new tracking technology. The NHL worked with sports technology innovator
Sportvision to embed tracking devices inside the pucks and on the back of
player jerseys. To help capture the movements of the puck and players, infrared
cameras were placed all around the Air Canada Centre in Toronto, where all the
World Cup games took place.

Together, the cameras and tracking chips were able to
generate large amounts of data including puck and player speed, distance
traveled, puck trajectory, player ice time, zone time, shots, shot distance,
shot direction and possession statistics.

However, as with any experiment, not everything went
perfectly. “We had an issue early on with shift times,” Sportvision CEO Hank
Adams told Yahoo Sports. “When players were going off to the penalty box, [the
cameras] weren’t seeing their infrared tags. It was still counting their ice
time as they sat there.” (Sportvision later adjusted their cameras to fix the

Small hiccups like that are why the NHL and Sportvision
thought it was important to test this technology at the World Cup. They
previously used ref cams and tracking chips at the 2015 NHL All-Star Game, but
the game didn’t really push the technology hard enough.

“The data that came off the All-Star Game was at all-star
speeds, at all-star physicality,” said Steve McArdle, NHL executive vice
president of digital media and strategy planning. “It was different.”

That is, the technology was being used in a less competitive
environment. By using the technology at the World Cup, the NHL and Sportvision
were able to do a proper stress test, examining the system in competitive play
over two weeks and 15 games.

Now that the World Cup is over, it’s time for the NHL to think
about the potential for Sportvision’s data-gathering technology in actual NHL
games. This isn’t the first time the league has been associated with
Sportvision. The company’s co-founder, Stanley Honey, previously collaborated
with the NHL on the infamous “FoxTrax puck.”

FoxTrax was a cheesy on-screen graphic that made the hockey
puck appear to have a blue glow, which turned into a fiery red streak anytime a
player shot the puck. The so-called “Glow Puck” was a $2 million failure, but
it led to the formation of Sportvision in 1998. The company made its name later
that year when it developed the “1st & Ten” graphics system, which first
displayed the now famous yellow first down line you see in football games.

Sportvision’s tracking technology certainly has the
potential to transform the sport of hockey, as it provides deeper data than has
ever been available before. But while the innovation offers some very clear
benefits, skeptics question whether those benefits truly outweigh the costs.
It’s one thing to plant infrared cameras and tracking chips in one arena for 15
games. It’s a different challenge when you’re talking about 30 different venues
and 1,230 regular-season games.

“I’m not underestimating [the cost],” Adams told Yahoo
Sports. “To put all of this equipment in stadiums is expensive. So it comes
down to how we’re using the data, what the effects are going to be and what is
the benefit to the fans. Is it worth it?”

The answer to those questions are debatable. Although
analytics is starting to become more popular in hockey, it hasn’t yet
revolutionized the sport the way it has for baseball.

“It’ll never replace observation,” Adams said of the data
that comes with player tracking. “We can track players and the puck, but that
doesn’t tell you possession. The puck may be closer to another player, but I
have possession of it. There’s always going to be an element of human
