GLENDALE, Ariz. (AP) His time on the ice done, John Chayka would turn to the tape, spending up to 25 hours to break down the game just played.
He tracked every player on the ice, every possession, touch of the puck, calculating the impact of every decision or movement on the ice.
The attention to detail, to making himself and his teammates better, led Chayka to co-found his own hockey analytics company. Now it's helped him become the youngest general manager in NHL history, a meteoric rise even he didn't see coming.
