I know Chinook has certain Green Colored Glasses (tm)
, but Kawhi simply has the bigger impact offensively, besides a very good defensive focus. While both still have work to do in various areas offensively, Kawhi simply has more weapons to take on the opposition 1 on 1 if needed, something Danny doesn't really have on a consistent basis. This all plays a role even on defense, as we've seen in the first round series, where a solid coach like Carlisle could simply use Danny to hide and rest talented offensive players that are mediocre on defense (see: Calderon). Part of the defensive work includes making the other team's best offensive players work hard on the defensive end. Kawhi can simply make you pay for that: his post game is fairly good, and he has a fairly solid mid-range jumper off a curl or screen, areas where Danny still need to improve.
Kawhi has some offensive improvements to make on his own, like better footwork, better finishing around the rim, keep working on his shot (including freebies), and more trust in his offensive game and less hesitation, but overall, he's ahead in the development curve than Danny (at least on that side of the court).
