There are several different ways to try to quantify an individual player's contributions to his respective team's overall results. From an offensive perspective, one way to do so is to look at what percentage of the goals being generated by the team are the result of the specific player's creation.
So in an attempt to sort through which players have been carrying the heaviest offensive loads this season, we'll strip second assists from the equation and adjust for strength of team. The reason for looking at primary points is because they've been shown to be more reflective of true talent, with secondary helpers being subject to more random noise and good fortune.
