id write them down on a lil card or something.
you need to have plays for every situation.
u need good running plays, good short and medium plays, good 20 plus yardage plays and last but not least u need a home run td play, which is mostly wr screens.
when u play someone good ur gonna need a scheme because they will be able to shutdown all ur passing plays soo ur gonna need to have them guessing as to if ur gonna run or pass from one or two formations.
