One in a million over and back

Rule 10-6-3d says that the contact should be ruled incidental provided that the opponent stops or attempts to stop on contact...in the case mentioned, the defender didn't stop on contact, but mowed the screener down...so using the rationale posted above, A2 sets a screen for A1 who is dribbling in the frontcourt...B1, guarding A1, does not see the screen and runs through A2, knocking him/her to the floor. You will have a no-call on that play?
