I had a partner a few weeks ago who from the T blew an out of bounds on his sideline and immediately and emphatically threw his thumbs up for a jump ball..from the L I was pretty sure who I saw who it go off of (near the corner), but it happened so fast and he was so emphatic in making the statement that he had no idea
that I just stayed out of it and put the ball back in play quickly...there were other issues this day with this partner though as well, too much to get into.....
