PC or nothing?

[cdaref]

Reference, please, for requirement that a person with LGP needs to fall over for there to be a disadvantage.

Plus, I dont see the OP saying the defense was not put at a disadvantage. I see the OP saying that he was wondering about whether there was or was not an advantage or disadvantage. He certainly doesnt say in his post: "there was no advantage or disadvantage." What he says is B1 had LGP and ballhandler A1 "slams" into B1, A1 goes flying and loses the ball.

Also please note that I am not mandating a PC call there. I am saying it is a tight one and that I likely would have had a PC call. I am saying I would reward the defender for LGP and then getting "slammed" into.
