Scorer as in skills/abilities to score? Lou or Ginobli. They have similar unorthodox games as well. Scorer means your skillset to me. How many different ways and how frequently you can use them to score.
Like Kobe, KD and Carmelo (prime) were dominate in every possible facet of offense. Low/mid/high post, wing, mid range, transition, open floor, penetration, at the rim, under it, 3pt range, didnt matter. That's why they are the most skilled scorers in the last 20yrs at the very least. Lou and Ginobli can score in ways and at clips that most starters can't. Odom deserves some recognition in this discussion as well. He was also a 6th man of the year.
