In high school every athlete that plays multiple sports at the school starts practice when they finish the before sport. Example baseball practice will begin for basketball players when the basketball season is over. When the last baseball or track or any other spring sport is finished the next sport is now football. It should be first priority. Football coaches should make weights, camps, ect. know to each player beforehand so that arrangements can be made to play the AAUs and go on vacations during the summer, but the top priority in the summer, sporting wise, should be football.
