Can someone explain how Iggy an upgrade over Deng besides being a flashier dunker and more durable?  Neither of them can create off the dribble.  I know people say Iggy has handles but he really doesn't.  Deng has become decent at shooting 3s, Iggy has a below average shot pretty much everywhere on the court.  Deng is a way better rebounder which is an extremely important part of defense.  Both are pretty good defenders, Iggy is a slightly better man to man defender.  

The only clear advantage Iggy has over Deng is his durability which I admit is important.  Honestly I just don't see how trading Deng for Iggy is a clear upgrade at all, not to mention Iggy's contract is way worse than Deng's.  

Someone please enlighten me.
