I don't see what LGP has to do with reaching for the ball from behind. Each of us has seen a guard come from behind and steal the ball from an unsuspecting dribbler, right? No contact, no foul. Therefore, when the contact is initiated by A1 clamping his arm down, how is that foul on B1? LGP has nothing to do with it.
Or in other words, what if he DOES have LGP, reach in for the ball, and get his arm clamped down? You're saying his position makes a difference?
