————————
For teams on the standard schedule, and assuming practice on Saturday, August 21, a normal schedule is 20 practices before the week 1 games.
For teams playing week 0, and assuming no practice on Sunday, August 15, a normal schedule is 21 practices before the week 0 game, and 25 practices before the week 1 game.
CIML, MRC teams will have 5 more practices than MAC, MVC teams. Perhaps it is an advantage (more time to get better). Perhaps it is a disadvantage (season wears out players).
