I posted this in another thread but Harden also does this "arm grab" move where he traps his defenders arm under his and makes it look like a foul. He did it more than a few times towards the end of last nights game against the Cavs. The NBA needs to crack down on this crap. It has to be one of the cheapest moves I've seen in a while.
Anyway, I feel like the game against Houston is more than just Harden vs Dwight. It's going to be a really good test of the Hawks defense.
As for the lack of pick-and-roll, that will come with time. The season is young. If we're still having the same concerns by mid-season then there's a bigger problem.
