which is exactly what a defending player might want
by hoople head
people complain about the delay of game penalty for a defending player shooting the puck over the boards in their defending zone but frankly before the rule was instituted that was a tactic alot of defencemen used when they got stuck in a bad situation. It was frankly a smart play, if the choice is turning it over or shooting it into the crowd for a faceoff and a line change.
If the league starts telling refs to whistle down the play every time they lose sight of the puck (like they're supposed to) without calling delay of game when a defending player lays on the puck smart coaches everywhere will start telling their players to do that.
It would be a great tactic on the penalty kill. Even if you don't allow a line change, the chance to let your penalty killers to breathe for 20 seconds, and then get a faceoff where they can possibly ice the puck and then get a line change is better than allowing play to continue.
