from Frank Seravalli of TSN,

Last spring, the NHL had an operational camera embedded in all four goal posts in every arena for 89 Stanley Cup playoff games.

This year, with the addition of the coach’s challenge, the goal post cameras would have required additional wiring and parts to make the feed available for replay with the new Hawkeye system in arenas.

But since the cameras located in the posts provided such little insight to the game, they are not yet functional in all 30 arenas with the Hawkeye system.

Why? Too often, the goaltender was blocking a view of the play or puck, even with the cameras positioned facing the goal line....

Rather than proceeding with cameras in the goal posts, the next course of action for the NHL may be to install cameras in the crossbar, pointing down toward the goal line.

The NHL experimented with crossbar cameras on an off-day during the Stanley Cup final and found them to be more useful for determining goals, but more challenging to install.
