Last week's drama involving UCLA star Shabazz Muhammad made clear what statistical analysts have long known about the NBA draft: Age matters. The Bruins have been listing Muhammad's birthday as Nov. 22, 1993, but an investigation by the Los Angeles Times found that Muhammad's birth certificate is actually dated a year earlier, making Muhammad 20, and not 19 -- older than the typical college freshman. If Muhammad declares for the NBA draft as expected, the difference could cost him a few spots in the lottery. It should.
