A lot of HS kids don't want to take PE and happy to do sport specific 7th period class. Some coaches will do crazy and unnecessary things and some will work on touches and ball skills during this time. Many HS coaches get too crazy and trying to make HS soccer year-round program. School my kids go to, have pre-season, Winter season, post-season and Summer league soccer, which essentially makes it a year-round. It's great for kids who could not afford club soccer and a nightmare for a club players.
