Pop is not experimenting for the sake of experimenting. He is not holding Bruce Bowen in the wings for the playoffs. The reason Bowen hardly played last night is because he cannot effectively defend Kobe Bryant anymore. Bowen hardly plays anymore at all because he has aged past the point of being a viable NBA player. Are people in denial about this? His game was predicated on tenaciously running all the court following his man. His lateral quickness on defense was unmatched. Now he is three months from his 38th birthday. He can't do it anymore. It's over.
The Spurs do not have an answer for Kobe Bryant, and will not have an answer. In addition to the issues with Bryant, both Pau Gasol and Lamar Odom are matchup nightmares for the Spurs, and the matchups get even worse once Andrew Bynum returns.
The Spurs need a role player to pour in 20+ even to stay close to the Lakers. They compete basically with heart and the wiles of experience. They cannot play Spurs basketball anymore. We see it, right? With Duncan hobbled, the only starter who is even an average defender is Tony Parker. Tony Parker. The Spurs have to try to outscore the good teams; having a "sound scheme" only works against the teams lacking offensive talent.
The Spurs are not going to win a championship trying to outscore people. It is not who they are. Even at full strength, who besides Duncan defends? Parker? Average. Ginobili? He's a gambler who gets steals but also gets burned. Thomas? A bruiser, but unathletic. Oberto? Clever, but that's it. Bowen? He's finished. Mason, Finley, Bonner, Gooden, Udoka? Not a defender in the bunch. That leaves George Hill as the "defensive savior." Pshaw. This team is made to go 55-27, be relatively entertaining, be easy fodder for the Lakers, and be there for the plucking by some of the other rising teams.
Going forward, "full strength" is going to be a mythical state for the Spurs. Ginobili is at or past the age when players who throw their bodies around like he does go into decline due to health. Tim Duncan wears down at the end of seasons now because he is the only frontcourt player who does any rebounding or defending.
We'll spend Marches and Aprils that used to be "SPAM" time telling ourselves, "if the Spurs can get healthy for the playoffs, they'll have a chance," and Mays telling ourselves, "if only the Spurs had been healthy, they would have had a chance." This is how it looks at the end of a great run in the NBA.
