As the 2017-2018 season is a rule-change year for USA Hockey you can expect a new rule book to be published in the coming weeks. PDF copies of the rule books and changes will be published to the usahockey.com website and they typically also offer video examples of more significant rule changes for educational purposes.
One significant change, outlined in the usahockey.com article enitled "Modified Shorthanded Icing Rule Delivers More Skill Development" announces the elimination of the waiving of icing for 14U and below teams when playing a man down (Penalty Kill). In past years icing the puck was allowed if your team was shorthanded but in an effort to force the creation of skill and creativity this change was made.
