Play #1: Illegal screen but A1 had already beaten B1 so I can see letting that go
Play #2: If I'm callng anything early is would be for defender pushing offensive player up to free throw line. Once I miss that I'm letting the play finish out.
Play #3: Really don't see much, no-call from what I can see.
Play #4: Need a block call on initial shot. Then we call a touch foul on the tap.
Play #5: I've seen rougher post play. Probably would get the TC foul but B1 fell more from the tangled legs than the arm sweep.
Play #6: I've seen this no-called in NCAA games so I wouldn't be too harsh on the officials for this one. Yes, it was a PC, but by the time a whistle probably would have come you have a defensive rebound and a run out. Not egregious IMO.
Play #7: By the time the screen becomes illegal A1 has the ball so C is now officiating on-ball and there is nobody with a good view of the screen. Maybe one of those plays the coach designs knowing there will only be one official strong-side.
Play #8: I probably would have got that first hand-check in the BC.
