The graphic you see below is from Sports Illustrated. It's comparing the shifts and productivity of NHL players. (For those who aren't hockey fans, NHL players come on and off the ice frequently during a game. A shift is the time spent on the ice by a player.) According to the chart, Ilya Kovalchuk, for example, spends an average of 60.98 seconds on the ice during each of his shifts. For the season, he has scored two goals and added seven assists.
Now take a look at the totals for Joe Thornton and Alex Ovechkin. What, exactly, are "G Goals"? I've heard of PP (power-play) goals, SH (shorthanded) goals and even GW (game-winning) goals, but not this. To co-opt a hockey term, it appears as if no cross-checking took place. For that, the editor earns two minutes in the penalty box.
