Regarding Crawford, do you watch baseball? Have you seen how umpires at times bait managers to push them over the edge?
OK if you want to say 'because it's done in baseball, then it's ok for basketball' which I don't necessarily agree with.
But the stuff that joey crawford has done, calling phantom fouls on guys that were nowhere near the basketball at the time (camby last year), the above call on tim duncan, whatever other youtube clips you can pull up of him, he is a maniac!!! this is not just a ref making bad calls, this is a guy who for YEARS has made things up on live television for the world to see, and has influenced the outcome of games because of it. and he is allowed to ref some of the most important games of the season!
And while he is the most outlandish example, my only point is that there are other refs who have done just as ridiculous things, only maybe one or two times. But they don't ever have to worry about being "disciplined" by the league, or losing their jobs. And so this reflects on Stern.
