Gus Malzhan's plan for Spring Practice hasn't changed in his time at Auburn. He likes to spread it out over the course of a month or a bit longer. He likes Spring Break to be in the middle to provide for a break (ahem, Michigan). He also likes to have at least one day of practice to clean up anything seen in the A-Day game.
Football programs are allowed fifteen practices during the spring period. The spring football game counts as one of those practices. There will probably be at least one other scrimmage the week or so prior to A-Day.
