I'm guessing you didn't hear Grant's call on that particular mistake. The way he acted, you'd think the extra player was actually standing in the middle of the paint, waving his arms and hacking Kings players as they tried in vain to point it out.
I must have seen it different than you. I think he actually
was in the paint, or just a step out of the paint, and actively guarding a man while we were trying to inbound. Right about the time the pass was triggered, he realized there were 6 on court, turned and sprinted off. He definitely wasn't off by the time the pass was inbounded, and he spent at least 2-3 seconds guarding somebody while our inbounder had the ball. That's not ticky-tack. I think a player not in the game has to be off the court when the inbounder is given the ball, right? I wish I hadn't deleted the recording because I'd like to look at it again, but I did rewind it at the time and it was definitely more egregious than a guy, back turned, one-foot-in, one-foot-out of the court.
