"Ball don't lie" is said when a player misses one, two or all three of his free throws after a questionable (read as: bullshit) foul call is made by an official. The ball is, essentially, the unbiased judge who will not reward the player by going in if the apparent foul was indeed bullshit.
Rasheed: That's BULLSHIT, man!
*Andrew Bogut toes the line and proceeds to miss his first free throw*
Rasheed: BALL DON'T LIE!
*Bogut then attempts a second free throw and misses again*
Rasheed: BALL DON'T LIE, DAMNIT!
'Ball don't lie' is more than phrase a player can call out to make a case that a call was made unnecessarily, it is also a mind-set and philosophy. Although Rasheed Wallace may come off to the public as an inarticulate NBA thug, some, like myself, believe that he is a deeper individual, both in intelligence and in a spiritual sense. 'Ball don't lie' is evidence of this hidden and sheltered brilliance exposing itself to the masses. The basketball philosophy Rasheed gave the world, that a basketball is a fair and unbiased being, is ingenious. I have a feeling that some NBA players may have adopted this set of thinking and think the exact phrase of "ball don't line" when NBA referee bullshit is evident. I believe Rasheed's philosophy extends beyond the shooting immediately after the bull call, maybe even influencing the outcome of the game (although the circumstances in which the call occurred would have to be significant). Radical, yes, but if we as a society have accepted crap like the 'Cleveland curse' can't we believe a philosophy like this.
Thank you 'sheed.
