Tony Parker did an interview with Bill Simmons for Grantland over the All Star weekend and in it he revealed how he was almost drafted by the Celtics in 2001.
Boston had 3 picks in the 1st round that year and when they were on the clock for the 21st selection the woman who gives players the team cap before hand came up to Parker and handed him a Cs hat and told him he was being drafted by Boston, unfortunately she then came back a couple of minutes later and took the hat back saying the Celtics had changed their mind and they ended up picking Joe Forte instead

Parker later asked Boston GM Chris Wallace what had happened and was told that he and coach Jim O'Brien had wanted to select him but that Red Auerbach had overruled them.
Boston stuff is about 9 minutes in.
