1) I developed a bad habit this year of not putting up my hand (stop clock signal) before a backcourt violation. I'm glad to see that others have the same problem (although the stop clock hand is probably not needed in NCAA mechanics).
2) I bet the official called it based on the bounced ball seemly hitting the division line (close), and not based on the player stepping on the division line (not close at all).
3) I wonder if the call, or noncall, would have been easier to make if there had been a "real" division line rather than a "ghost" line through a gigantic Final Four logo?
