This video is sped up slightly which makes everything look weird.

New Lead should be at halfcourt, minimum, helping out with the press. You have 9 players in the backcourt so he's gotta be back there. He might be there, but can't tell.

Trail needs to go across the lane and administer the throw-in on that side. You can see C start to go to new Lead, he thought it was coming across.

I don't really care for the OOB signal from Trail.

I don't really care for the 3+ PC signals from Center.

Kudos to the white coach for keeping his assistants in check at least a bit.
