One thing that always annoys me when Duncan is compared to other bigs such as AD or even a temporary like KG is how people ignore one of his biggest strengths which is his back to the basket game. Duncan's ability to post up back to the basket is a rare skill set that very few bigs have paired with his elite footwork made him unguardeable 1 on 1. Go watch some of Duncan's old games and watch how it only takes him literally 1 second in most cases to back down a defender and score and at most only 2 seconds. There isn't a big man currently in the league that can post up like Duncan can including Davis. Davis is a player who relies heavily on facing up and shooting jump shots along with driving to the basket for a layup or dunk. His game is more similar to David Robinson than it is Duncan.
