you act as though teams are actually employing this as a system or some focal point of their actual strategy. i am confident that i have seen enough games with enough different teams to say unequivocally that is not true. teams value puck possession way too much to risk turning it over or giving their opponents yet another opportunity to win an offensive zone faceoff and get a scoring chance. i don't know a coach alive that 9 out of 10 times wouldn't prefer to maintain possession and try to break out and attack on the rush than throw the puck down the ice in a perhaps less than 50/50 situation and then give their opponents a legitimate scoring opportunity should they win the ensuing faceoff. many of the coaches i have talked to over the years actually chart scoring chances off of faceoffs...and from what they tell me, the team with more is usually the team that wins the game.
that isn't to say that teams don't try to hit the home run pass, but that happened with the old icing rule too. the fire the puck into the NZ off a dzone faceoff and try to fly a winger play isn't new...that went on with the old rules too. does it happen more now? it's debatable. i honestly dont know either way. if it is, it's not by a significant enough amount that it's having a big impact.
perhaps we should put the two line pass rule back into hockey? less home run pass attempts would equal less icings...
