David Locke looks at players based on relative scoring efficiency. Worthwhile but scoring efficiency is about 50-60% of factor level offensive impact or 25-30% of total impact considering defense, on average (more or less depending role / usage level). Fairly obvious but it is something that should be noted, keep in mind. Not the whole story.
