"It's all about the coaches, and it's really the assistant coaches who are giving information to the head coach," NHL director of digital business development Chris Foster said. "Specifically, it's the coaches on the headset talking to the video room who are then giving the information to the head coach."
Foster said the NHL, in consultation with video coaches from various teams through workshops last season and at the 2018 NHL Draft, built the app to have player usage (time on ice) and face-offs at the forefront because that information would be most valuable to coaches during games.
On the app, face-offs are broken down by success rate per zone and side of the ice, against specific players and a color-coded visual graphic for how a player has done in his past five face-offs.
For time on ice, there is a customizable threshold coaches can input for each player, essentially the amount of minutes he is expected to play in that particular game. If a player goes over the expected minutes, the graphic turns red so coaches can quickly see that information.
"Since it's happening on the bench and really you have seconds to look down, you need some clear visual queues, color-coded queues to give you insights without having to read the actual text, that you can just in a glance look at," Foster said.
The app is customizable for coaches to give priority to the team and player stats they feel they need most.
A deeper dive into the app will give the coaches access to an array of team and player statistics, including shot attempts, unblocked shot attempts, chances for and against, and success rate on shootouts with forehanded shots and backhanded shots, a potentially useful tool for goalies too.
