While I agree with the sentiment and don't totally disagree, there is a slight difference. Chicago was always going to get the worst pick in the lottery, while IT could be considered a good luck charm if we moved up into a top spot. The whole thing seemed a little desperate from Chicago's point of view. With everybody talking about Butler as a potential trade target, Chicago was basically calling their bluff.
It's all about perception in this case. IT really is seen as an integral part of the Cs, while Chicago and Butler may have some dissension. Obviously if they don't trade him, their point will be proven, but if they do decide to seek out offers, they are at least letting teams know he won't come cheap.
