Pitch rule question as pertaining to option football

[Steel Town Tough]

Can AB or Dre/whoever LMK about the pitch rule.I have been working with an option package and need to know MPFL basic rules on it.When you can just call pitch or when you need the sticks.I understand about RB needing to be behing the QB and all for a backward pitch.The option is a great attack to force your opponent to cover the field or else.The pass is an option right up until last stoppage if you need it.Thanks for the help--STT
