Maybe terrible is too strong of a word. He's more of a me first player who blames losses on his team and not himself. He's ****ier than he has the right to be and isn't the guy you'll see cheering on him teammates, but pouting on the sidelines.
Then again... you should take this all with a grain of salt, because you never really know whats going on behind the scenes.

I like Iggy cause he's a great defender. Hes not consistent from 3 range, but has a decent pullup in midrange which he relies a bit too much on. His main strength will be in transition where with the Knicks he can create major havoc. I actually think he's a better fit for us than Melo, in that we need a 2 more than a 3 and he'll be less of a strain on our salary cap.

I'm mixed about him, but would still rather have Varejao for intimidation.
