In pro basketball today, it's good to be a stathead. Coaches use stats to decide who should be in the lineup each game, how to defend against each opponent, and when to send in a sub. Players use stats to train and prepare and to get an edge after the opening tip. And sports reporters rely on data to describe the games. Today's hoops fans, who always want to be in the know, get more out of the action by joining the ranks of the statheads.
