Karl Malone? What?It is true that anything can happen but it looks like it may take a historic fluke for Houston to pull through. Harden's defense is all about trying like you mentioned earlier, but it clearly affects his offensive game. He simply doesn't have the stamina to play high-level defense and high-level offense against a team like the Warriors.
Chris Paul is extremely underrated by many imo. For example, this the first time he's ever played with a guy like a Karl Malone, and he happens to cruise into the WCF.
