Forget Nash, he's old and doesn't play defense. The latter is our major problem.
Question should be: How good could this team be with Rajon Rondo?
On a sidenote: If the Lakers really manage to get Dwight, they're in for another dynasty. This man is an absolute beast. It has to be the best body in NBA history. A true role model for other athletes in terms of work ethic and nutrition. That guy keeps about 5% body fat over the course of a season...really impressive.
