In pro hockey today, it’s good to be a stathead. Coaches use stats to decide which players should be on the ice, when to reshuffle the lines, and how defend against each opponent. Players use stats to train and prepare and to get an edge after the puck is dropped. And sports reporters rely on data to describe the games. Today’s hockey fans, who always want to be in the know, get more out of the action by joining the ranks of the statheads.
