Legal or Illegal Pitch

I'm not doubting that behind the back is illegal in FP. It's just that the FP rules don't say, as do the SP rules, "The pitcher must not pitch the ball behind the back or through the legs."

Exactly what is "the straight line of the body"? A line between what and what?

I agree the rule is not as explicit as the SP rule, but which of the various "straight lines" would the ball, hand, and wrist follow through to be forward of?

Shoulder to ground?
Head to ground?
Midpoint of trunk to ground?
Across shoulders horizontal to ground?
Across hips horizontal to ground?
Back of the ear to the ground?
Hip joint to the ground?

Makes no nevermind - none would allow a release behind the back.
