In response to being run off the court by the Los Angeles Lakers in the 2001 Western Conference Finals, having no answer whatsoever for Kobe Bryant, the Spurs turned to Miami free agent swingman Bruce Bowen in the offseason to shore up the team's perimeter defense.
The results were immediate; Bowen was virtually without equal in the league as a perimeter defender, and his contributions more than offset the decline in David Robinson's play as the Spurs adopted a new paradigm for elite defense -- Duncan anchored the paint while Bowen took care of the opponent's best outside scorer. No double-teams were needed, and the rest of the players could play straight up. With these two anchors and a solid scheme, teams usually could not score enough to beat the Spurs unless the Spurs were just wretched on offense. This formula led to three NBA championships, each of which included a few examples of the Spurs' patented 75-72 grind-it-out game which made diehard Spurs fans come to regard great defense like fine wine, while making casual NBA watchers claw their own eyes out.
Bowen possessed uncanny lateral quickness, which, along with his tenacity, meant he could stay with his man in situations where lesser players would have been neutralized by quick moves and screens. He also knew all the little tricks to get inside the opponent's head and throw him off his game. Bowen showed trememndous durability and longevity; whereas typically players who depend on lateral quickness start to decline in their early thirties, as late as 2007, nearing the age of 36, he spearheaded a defensive scheme that totally neutralized LeBron James in the NBA Finals.
With Bowen's brilliance on defense, the Spurs could utilize other more pedestrian defenders on the perimeter as part of their scheme. If the player was in the right place when he was supposed to be, everything worked OK.
For all Bowen's durability, however, Father Time could not be held at bay forever. Bowen started to show signs of slowing down in 2008, and in the current season he has been reduced to a situational defender who does not routinely play heavy minutes. Nearing the age of 38, it is clear his NBA career is nearing its conclusion.
Without Bowen to anchor the perimeter, the Spurs simply cannot be the elite defensive squad they once were. A healthy Tim Duncan would not be able to do it alone; with Duncan hobbled into mediocrity, the Spurs are sitting ducks on defense. Their good scheme allows them statistically to rank among the better teams, since the scheme is sufficient against the weaker NBA teams who don't have elite scorers requiring extra attention. However, the Spurs have no answer for the better teams. A team as pedestrian as the Dallas Mavericks can make the Spurs look like a bunch of old fat guys at the Y.
Gregg Popovich has attempted to compensate for these new defensive woes by focusing more on scoring. Perhaps with a healthy Tim Duncan and Manu Ginobili, the team would be dynamic enough to compete against the better teams. But as it is, it is left to Tony Parker to generate nearly all the offense by himself, and as good as Tony has become, not even Oscar Robertson could carry a team to a championship; he needed Kareem Abdul-Jabbar.
Hopefully, the Spurs can put their injury woes behind them as this season ends, though with Duncan having so much wear and tear on his knees after so many 95+ game seasons in a row, and with Manu well into the age range when players like him fall into decline, such hopes are doubtful. One notion where there is essentially no hope, however, is that the Spurs could regain their defensive prowess. That prowess depended too much on Bruce Bowen, Bruce Bowen was too unique a talent on defense to hope for a replacement, and the player he used to be isn't coming back.
Barring a personnel miracle, the Spurs will be trying to add a fifth le sometime in the next three years by hoping that Tim Duncan's creaky knees and Manu Ginobili's fragile ankles can hold up over the gauntlet of long season enough to help Tony Parker outscore the likes of the potent Lakers, ascendant Cavaliers, young Blazers, and whatever other new powers emerge in the league. I think the chances are near-certain that Duncan will retire with his thumb bare, unless somehow he ends up his career on some other team, just along for the ride on their le run.
The team the Spurs have been for the past ten years is already gone. The sun already has set, and the light we still see is just the fading afterglow. Make sure you don't lose those championship DVD's, because they'll be the only way you'll be able to watch the Spurs go deep in the playoffs for some time to come.
