Great video for discussion.
I would agree where there a several in there where he doesn't have to go down. He could bounce back or fight to keep his balance. The fact that he doesn't have to fall doesn't negate what the offense is doing in these situations. I agree there is one where he may still be moving in on an airborne shooter but other than that I can live with all these calls.
If there was an official who wanted to no call some and say they felt like the contact was incidental and the embellishment was why he became disadvantaged I could probably live with that on a couple. But if there are blocks (except the airborne shooter play in question) or tech's being called on any of these I would not support that.
