Forget Varejao, and go get Demarcus Cousins. He's young, rebounds really well, and plays down low for the most part. His upside is higher than Varejao's and he could be an absolute beast playing next to KG. I also think he needs someone like KG around him right now to keep him honest.
Rondo, Dooling, and the Clippers pick for Cousins, Garcia, and Fredette. It works on trade checker.
