Real talk.
The NBA is increasingly becoming a league of haves and have-nots (it's always been that way really, but much moreso now), and a good system/good coaching can only take you so far as last year's WCF proved.
With that being said, the harsh reality is that no significant FA has ever signed with SA (from another team). They have drafted a very good bigman (D-Rob), and the greatest PF of all-time (Duncan) and ridden those two to 25 years of compe ive basketball--and 14 years of being contenders.
The window has closed on this bunch now, and no heir apparent looms on the horizon. San Antonio is doomed to become the Atlanta Hawks for quite some time after this.
Taking all that into account, have we seen the last of the Spurs ringing?
