I enjoy that you state this as if it is some deformity or abnormality that can't be fixed. First, it's actually incredibly common among humans. In fact, I read that as little as 1/4 of the world's population actually has equal length legs. A simple shoe insert alleviates the problem in many cases, especially for one as little as a half inch. Do you ever have one pant leg that drags on the ground while the other doesn't? If you do, you probably have different length legs. To the topic at hand, I don't think KP can/will be fired until we see this team under another coach first.
I can only imagine the howls and ridicule if KP had taken an oft-injured scorer while a (supposedly) healthy was pushing for defensive player of the year honors ... all we'd hear about is how Roy and Durant take away from each other's game and there aren't enough touches for Aldrdige (not to mention how porous our interior defense is). There's no winning unless you get the healthy and productive guy, end of discussion.
Should have made it a public poll. Scratch that, I think we can guess who voted for Yes: jplrrtklrltkerkl and mixum. Anyone who thinks this should even be a question needs to get their head checked.
