An excellent official considers what his partners can and cannot see before making a call out of his PCA.
That is the whole reason that a secondary whistle should be late. "That's the C's call. Wait, maybe Jack can't see it. I have to call this." Tweet

And I saw the play in the OP. I have no idea why the Trail didn't call it, other than he was usually near the division line in the trail and probably bailed on the play. It was definitely a foul, and APG did have patient whistle. The team on offense wasn't running any plays through the low-post all game. APG was out wide mirroring the post and the foul happened no more than 3' from him.

I was part of the locker room discussion afterwards. The folks who didn't like the call never said it wasn't a foul, just that the Lead shouldn't be looking out there. When I'm the Lead out that wide and a 3 goes up from the corner, I'm peeking at the shooter also. Doesn't take but a split second.
