MichiganHockey.net brought up an interesting rule change that the NCAA is considering this year, that icing will ALWAYS be called. This includes when a team is on penalty kill!
Under this proposed change, a shorthanded team would not be able to ice the puck freely. While this change might sound small to the casual observer, it could have a huge impact on many aspects of the game, from killing the flow of the game (imagine a team icing the puck ten times during a major or minor penalty), killing the legs of the penalty killers (the team who ices the puck cannot change lines and having to do a soft clear might not give you enough time to safely change on the fly), and even perhaps on recruiting. None of the the NHL, AHL, ECHL, Canadian major junior hockey, or any league has implemented such a drastic change, and potential recruits might opt for routes other than college hockey feeling this change won’t help their development.
This seems like a crazy change, and the coaches seem to agree in MichiganHockey's article (follow for more info).
