I like the idea of having Card and Padgett as our two power fowards. We lose some size but they bring so much more to the rotation that Cato, Spoon and MoTaylor.
Personally, and I'm not black or white btw, I think this kind of stuff is best dealt with by ignoring it. You know it was a joke, so don't get "frosted". Unless you feel he's really making racial slurs, then that's another thing. But you implied that you knew he was kidding, so you have no reason to be offended.
