Yeah you're right, he certainly has his warts. Plenty of them. Also you are right about Harden, when Dwight went out he put up MVP numbers and led his team to wins alone. I don't think Harden-Dwight chemistry is all there, I think it's mainly because Dwight has it in his mind that he's Hakeem and demands post up. A lot of us wanted SVG as a coach here because he's the only guy that understood that Dwight at his best is cleaning the glass, blocking shots, and finishing plays not starting them.
As for Josh...it's a risk. He could come in here and ruin things definitely. He's going to put up his shots but this team has a very very defensive mentality. If Dwight misses a guy and gives up a easy layup you can see Harden give him a glare. You can see guys get upset and talk it over whenever easy buckets are given up. Point is, it's going to be very clear to Smith that you come here and you play defense before you play offense and I hope that gets him going.
