I'm that's how defenders think, Harden just master his style so much and we've seen improvement year after year.
Harden is a good shooter and knows how to fish foul by driving the ball inside most of the time, he will make more shots if he continue to bring the ball most of the time, and so far they are still doing good with their 6-4 last 10 games record.
Harden is doing the right thing base on his current doing. Might be annoying to anyone but his style is effective.
That's what he does, some will hate, some will appreciate, just like Mayweather in boxing, his style is annoying but that's where he is effective at.
On the other hand, producing 30+ or 40+ points in a streak is really a difficult task. That's how good the last season MVP is.
And he'll probably continue to produce this score now, I'm guessing 30+ average is easy for him going forward to this season.
