I’ve created a kind of crazy system. I do a random number generator. 1-9 is player lock on that position 1 Pithcer 2 Catcher 3 1B etc. number 10 is a super sim, 11 is play all batters sim pitching 12 is play all pitchers sim batting and unlucky 13 I play the full game. It mixes it up pretty well.
Another way I’ve done it with a number generator is to do 1-9 and sim to the inning that it gives me and play from there.
