1. I don't have the defender moving into the shooter.
2. The NCAA RA rules currently make no mention/exception/allowance for a player blocking or attempting to block a shot.
3. The key in my mind, and what I was driving at, is what JRut and a couple of others mentioned briefly, and what I asked APG: That, in this play, the official needs to determine if the contact is illegal, as specifically mentioned in the RA rules - because this secondary defender cannot establish initial legal guarding position in the RA - regardless of what they do after they establish there (i.e. all of the verticality/clean block up top discussion), or if it was incidental. That's why I posed the question of same situation, but defender never leaves the ground, and the shooter still ends up on the floor like they do in the film clip.

We (I think) all understand/know that a play where the defender establishes their guarding position in the RA and then contact occurs with the defender in/above the RA that results in both players hitting the ground will be a blocking foul (flopping/atypical situations aside). What I'm asking is when the defender doesn't hit the ground, or get seriously displaced, but the shooter does, what should we have?

Edit for this coach discussion with official after my play:
Coach: "HOW IS THAT A NOT A FOUL?"
Official: "THE DEFENDER DIDN'T DO ANYTHING ILLEGAL, COACH."
Coach: "THE DEFENDER CANNOT ESTABLISH LEGAL GUARDING POSITION THERE! SO DOESN'T THAT MAKE HIM ILLEGAL WHEN CONTACT HAPPENS WITH MY SHOOTER?"
Official: "I HAD ONLY INCIDENTAL CONTACT THERE, COACH."
Coach: "THAT'S A HE** OF A LOT OF INCIDENTAL CONTACT THAT RESULTS IN MY AIRBORNE SHOOTER LANDING ON HIS A** UNDER THE BASKET!"
Official: "................"
