This is the thought I had when reading the OP. The double-team on the wing probably blocked the Trail's view of the shooter in the corner.
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
