With two solid perimiter defenders in Crazy Pills and Battier, keeping Nic on the floor allows them to focus on Roy and ignore Nic, who is a non-factor on offense. Rudy keeps them running around on defense, and more importantly, let's Roy go one-on-one with either Artest or Battier.
I really like the lineup with him at the two and Roy at SF. Plus, Rudy is just plain bananas.
Who's with me?
