No.
If you think KG is done, what's the point of becoming a player in 2010? Adding Joe Johnson isn't going to make us a contender if it's at the expense of losing PP and Ray. Maybe if you could guarantee that Wade comes here, but given our climate and the message it would send if we blew this team up, I wouldn't hold my breath.
If he's not done, then why are we breaking this thing up?
