In our area, each assignment is a double header. The only exceptions are if a school does not field a team in that particular category. VG-
VB play at one game site while JVG-JVB play at the other site. It has been like this for many years. Some conferences (usually smaller schools) play all four games at one site and one night. On these nights, the JV games cut quarters down to 7, sometimes 6 minutes per. No reduction in pay. Good night to call JV games.
