Those were alot of the old Pete Maravich training drills. i learned those as a kid watching Maravich on a segment of Red Auerbach on Roundball. Could do most of them but not all(juggling 3 balls for example couldn't do).
I'm pretty sure Miller was in a commercial for the Olympics too. Some kid dribbling a ball all over, sleeping with it etc. IIRC they had to do it for free so as not to void his amateur status.
