I have always been of the view that an offence should not call a time out when you get the ball with 10 seconds left -- especially if you have a good point or a smart player with the ball as you near halfcourt. Your going to get a better shot like that, then allowing the defence to call a time out and set up.
I would have not had an issue with Dixon calling a timeout the moment the 2nd free throw went in. But once it seemed that Syracuse was possibly a little unorganized you must have the discipline not to call a timeout.
