The NFHS announced some new changes yesterday for the 2017-18 season. The most notable is the extension of the coaches box from 14ft to 28ft. The ultimate decision will be left up to the state associations. The NFHS cited coaches being able to communicate with their players as the main reason for the change.
Additionally, the NFHS added a misconduct warning for coaches where play will be stopped and an official warning will be recorded in the score book.
