What do you think of the helmet cam that Sportsnet has added to one Ref for their broadcast? I thought it was interesting to see the Virbata goal initially ruled a high stick and no goal, but after a video review, the on ice call was correctly reversed in the Calgary / Vancouver game tonight. They even showed the ref's view from his camera in the arena.
It makes some sense to have a camera on the ref's helmet, as most times, especially on goals, he should be looking directly at the play and may have a camera angle that no one else in the building should be able to have.
