What a tangled mess this rule is. So suppose that in this play B1 remains out of bounds and B2 manages to cause a charge that's in the RA. If I've read this thread right, that's a charge because this is not an outnumbered fast break. But if B1 steps in just before the contact from A1 we have a block?
