When you do gameplanning and you have the 40 offensive and defensive plays you pick to practice, are those the ONLY plays that will be called in game or can any of the hundreds be called but those are the ones that are practiced ?

the plays you pick (40 for offense and I think 30 for defense) are the only plays that will be called in the game. So probably spread the selections out a bit for short, medium, long pass as well as inside and outside run.
