Marist vs Iona Fastbreak Dunk Block/Charge??? (Video)

[bainsey]

I started a different thread with the following question, but it was before I saw this video, and since the video is pretty accurate scenario of what I had in mind, I deleted that post and going with it here.

So, everyone here knows (or should) that LGP is required before a shooter leaves the floor to draw a PCF. The usual visualization of this play is that the defender is stationary. Let's try something else:

Let's say A-1 drives, closely guarded by B-2. In a whole quick motion, A-1 stops his dribble, B-2 obtains LGP, A-1 goes airborne and forward, and B-2 backs up and draws contact from A-1 after the ball is released.

Assuming the contact is advantageous, we would still have a charge, yes? Even though, by rule, LGP is maintained by moving backwards, is there any instance in this scenario where it could be argued that LGP is somehow lost?

(BTW, I have a PCF in this video. I have LGP before the shot is released, moving backwards, and a displacing knee to the face.)
