It's interesting, you see "lead" make the "count the basket" signal, but you never see "trail" - who handed the ball to the inbounding player - and that's supposed to be his call. He seemingly never gets into the play, and I think (IMHO) that a competent official at that level should have been able to get close enough to that play to see it. I can also say that a cell phone video from 25-30 rows up doesn't show when he gathered the ball (read: put both hands on it). I mean, does it look like a travel? Yes. Can anyone offer conclusive proof he did? No.
