Guards
Steph Curry is and has been one of the best guards in the game for a few years now. His ability to score just comes second-nature. But he had his great run as the best offensive player in the league. From what we saw last season, James Harden now holds that title. The Beard can attack a defense from every facet of the game; in the paint, beyond the arc, mid-range, free-throws (and drawing them), creating shots, and simply everything capable of an offensive-minded player.
Just between Harden and Curry alone, the advantage goes to Harden.
