Ok first of KG gives you blocks, rebounds and EVERYTHING. He also worked on his game this summer. Which means he's still better then Darko which he's only going to get 10/6 and Smith, who we'll have to fight for the starting job.
Then to top it off you let go of Butler, he's finally finding his groove. As for the third player you got of then trade Harris aint really going to do that much for ya man.
