seriously thou. I think Iman and Douglas will play well in the back court, possibly better if they played together.
At first I cringed, but then I thought about it...
Both TD and Iman are more than capable of bringing the ball up the court for halfcourt sets, and Iman looks a little better at running and finishing.
TD has trouble being a playmaker, but he's a very good outside shooter. And with his shoulder all fixed, he should be less streaky, too. So once the ball is in motion, plant him outside to stretch the floor.
Meanwhile, Shumpert can get the pick and roll started with Amare or Melo, and look for opportunities to slash to the basket because he's such an athletic finisher.
Of course, on the other end of the floor, they could potentially be one of the toughest defensive backcourts in the league.
