I think this is the C's play all the way. He not only saw the play, it was on the other side of the lane. The Lead is guessing IMO because he is looking through the back of defender at best and any call he could not see the space between the defender.
I have also worked with the Center official many times over the years. I can tell he was not happy with the Lead on that play by his body language and facial expression.
And I never get why people think the Center cannot see a secondary defender. He beat the first guy, you transition to the next play.
The Lead IMO was not hustling to get to the end line in the first place and then did not "post" and made a call without giving the Center any chance to make his own call.
But it is a good learning tool.
