At least that's what one of their many owners seems to think. Via Michael Cunningham of the Atlanta Journal-Constitution (emphasis mine).
"Derrick Rose goes down and the No. 1 seed is playing the No. 8 seed and everybody is like, ‘Chicago is down 3-1, that’s what you should expect with Derrick Rose down.’ Well, we’ve been playing these playoffs without Zaza, without Al Horford and Josh Smith should not be playing. Our center is Erick Dampier, God bless his heart, but he looks like a granddad. (laughter) He’s a great guy. It’s difficult enough to win a playoff series, but when you lose your whole frontline and nobody ever says, ‘Gee, you are out playing with guys that are hurt.’"
Juwan Howard is somewhere objecting to this classification.
