Look, the C's have no chance of WINNING IT ALL without KG. KG isn't having surgery, and he wants to play as much as anyone in this world.
Why would Doc say he doesn't know when he's coming back, but he definitely could at some point? He has NOTHING to gain by that. Then all he will hear is questions about Garnett. However, Doc is a fairly honest man, so he just says don't expect him to play, etc, etc, but never rules it completely out.
KG will be back at some point in these playoffs. All the sheep in the media and in the fan zone will be proven wrong. Don't believe everything you hear/read.
