Whistles needed? (video - 4 plays)

[JugglingReferee]

1. I am indifferent for a foul here. I do believe that B had position with his right foot. But the lean and shoulder was likely outside his cylinder against an airborne defender. I'm ok with a no-call here, but I'd lean slightly to a block.

2. Is the potential foul at the double screen up top? From what I can tell, I have nothing. But again, I'm ok with a foul call.

3. Looks like the foul is for white climbing black's back. I don't have a foul on this play. I've got a great effort though.

4. White foul. He initiated the arm lock. Tough for the L to see though. If one waited to see where the ball went, that's a great method for this level of play. At other levels, I say grab the white foul.

I'm always going to put a whistle on this. To me it sets a dangerous precedent to let defenders lean into airborne players, especially with above-the-rim play.
