The Spurs may have no other choice than to stand pat, but in doing so they've not solved any of the issues that plagued them a few months ago. I certainly understand the financial constraints the Spurs are under. That's just the way it is. Still, if the Spurs start next season with exactly the same team, as presently constructed, then will continue to be defensively inferior and a notch below the big dogs on the block - OKC Thunder - for yet another season and THAT is a concern.
This was all made very clear in the recent playoff series. Looking at both sides of the coin, scoring points is one thing and the Spurs can do that pretty well. Yet the Thunder clamped down on the Spurs and were able to generate key stops at critical moments. They did so by taking away the Spurs strengths, negating their pick-n-roll offense and thus killed their ability to score. On the other side, the Thunder were able to raise their level of offensive play when they most needed it. They literally scored with ease - off turnovers, runouts, offensive rebounds and putbacks, etc. The veteran Spurs were left powerless to do anything about it.
Stand pat all you want so long as everyone knows that improvement for this team IS NOT coming from within - contrary to what Pop and RC have told us so far. Improvement must come from one or two positional upgrades, which the Spurs. at this moment, are in no position to make. This isn't a good receipe - especially for team who has 2 major stars on the wrong side of 30 years old. Osmosis is not going to close the talent and skill-level gap between the Spurs and the Thunder.
