At Tufts, the hockey team is using an iPad and GoPro camera as tools to help its goalies. The devices are part of a package developed by Double Blue Sports Analytics, launched by Dan Kerluke, a former University of Maine player and assistant coach. Users place the camera on the glass, preferably above the goalie. The camera captures every sequence that is critical to a goalie’s analysis of the game, such as shots, saves, screens, passes, entries off the rush.

Either during or after the game, a goaltending coach tags the events on an iPad. If an opponent takes a shot from inside the blue line along the wall, the coach will drop a pin on the approximate location. The coach will note if a goal is scored off an extended cycle. A tap on the screen will tag where the puck beat the goalie — high glove, low blocker, five-hole. During video sessions, the goalie can study every save made and missed. Even if a goalie’s coach is elsewhere, Double Blue’s iPad application allows for remote instruction. Once a goalie’s game is captured and tagged, the video is uploaded to a cloud server. The coach downloads the clips and makes notes and corrections via voiceover, telestration, and annotation. The coach pushes the video back to the goalie for review.

“If he’s given up eight high-glove goals, you can click on the shot chart and see all the videos attached to those eight goals,” Kerluke said. “Instantly for a goalie coach, you can go through those high-glove goals and find out what the deficiency is, then work on something in practice to make that improvement. As a goalie coach, to aggregate 10 games’ worth of goals against can be 30 or 40 hours of work. This technology extracts that simply and gives it meaning.”
