While there weren't a lot of changes to the game of basketball for the next/upcoming season, there were a few that require you to keep abreast. An exception to the backcourt violation and a clarification regarding specifications of the ball comprise the changes approved for the 2018-19 high school basketball season.
The National Federation of State High School Associations (NFHS) Basketball Rules Committee recommended the changes at its April 9-11 meeting in Indianapolis, and all changes were subsequently approved by the NFHS Board of Directors.
Rule 9-9-1 states that “a player shall not be the first to touch the ball after it has been in team control in the frontcourt, if he/she or a teammate last touched or was touched by the ball in the frontcourt before it went to the backcourt.”
An exception was approved to note that any player who was located in the backcourt may recover a ball that is deflected from the frontcourt by the defense.
