When: February and April 2012

There's one thing that will automatically get an athlete in trouble during games, in press conferences, on the radio, anywhere: Messing with the referees! You don't touch them, you don't say anything vulgar to them, you don't threaten them, you just don't do it. Rondo ignored all of these back in February when he decided it would be OK to throw a ball at a ref after a bad no call and was ejected. Apparently the lesson wasn't learned as last year in the playoffs in the video above, he thought it'd be OK for him to bump a ref after what he thought was a bad call. Instant ejection and suspension for Game 2 of that series for Rondo. Do it again and see if David Stern doesn't fine you six figures or more, bro.
