Bill Russell, known as a single-minded competitor when he played for the Boston Celtics, was recently interviewed by a writer for the New York Times. The writer asked about a player being subjected to boos and taunting by crowds. Russell, named as the greatest player in the history of the NBA in 1980 by the Professional Basketball Writers Association, had this to say: "You know...my youngest child asked me one time, 'How do you handle people booing you and saying unkind things about you?' I said, 'Me personally, I never accepted the cheers, so I didn't have to worry about the boos.' When I was playing, there was nothing outside the lines."
