Absolutely not! I'm a Celtics fan.
I won't hold anything against KG or Pierce, who aren't the driving forces behind this nonsense, but I won't be rooting for Doc and I certainly won't be rooting for Chris Paul, Blake Griffin, or Donald Sterling.
I'll treat KG and Pierce how I currently treat Youk as a Yankee. I hope he collects his money and spends the season on the DL, in no way negatively affecting the team I root for (Red Sox, Celtics).
