With about 40% of the schedule by the wayside, the sample size is large enough to start analyzing how this year's Spurs team historically compares to the rest of the squads in the Tim Duncan Era. There's still a lot of season left but we can get a decent idea about what type of team we're watching this season.
This first graph has Pop's favorite stat: field goal percentage allowed. I also included offensive field goal percentage to compare.
As you can see, the field goal percentage allowed is a far cry from earlier in the TD Era but it there is at least an improvement from last season. Offensively, there has been a huge improvement -- to the point that this year's team shoots much better than any other team Duncan has played on.
This next graph looks at field goal percentage differential (field goal percentage allowed minus offensive field goal percentage):
This is a very promising graph. Currently, the differential is higher than any championship team since the 1999 squad. It also illustrates a big improvement from the last two seasons.
To look at it differently, here is points per game and points per game allowed:
This graph isn't as pretty as the two above. Even though the Spurs are holding teams to a lower field goal percentage, they are giving up more points. While the offense has improved, it is partially negated by the decline of the defense.
Here is the point differential throughout the years:
Again, this shows improvement for the Spurs over the last two seasons -- but there is still a ways to go to reach the level of the last two championship teams.
Since the above offensive numbers are impacted by pace, here's a look at more advanced stats: points scored per 100 possessions and points allowed per 100 possessions. This normalizes the pace across the era to make it a more even playing field prior to the comparison.
This graph shows that while the Spurs are giving up more points than last year, they are giving up fewer points per possession. In other words, the faster pace this team is playing at is masking their defensive improvements.
This final graph shows points scored per 100 possessions minus points allowed per 100 possessions:
When pace is normalized, it appears that the Spurs aren't quite as good as their field goal shooting makes it seem yet they aren't as bad as the points per game comparison. This middle ground is probably the most accurate picture of this year's team so far.
Conclusions
1. This team's offense is really good. All the above graphs show that this team is the best scoring team of the Tim Duncan Era. Considering the turnover issues we've witnessed, the slow start by a number of key players and the offseason overhaul, this has to be both surprising and exciting. What happens if this team continues to gel and becomes a well-oiled machine? In theory, the rest of the NBA should take heed.
2. The defense still isn't at a championship level, however it's safe to say that this year's team is a better defensive team than last year's team. Almost every year, the Spurs get much better at the defensive end in the second half of the year. If that happens again this season, perhaps they can get close to the level of defensive played by the 2007 team. Unlikely but it is at least a goal to aim toward.
3. Offense is important to the Spurs winning champions. Yes, defense is the most important, but the offensive improvements from 2004 to 2005 and 2006 to 2007 were huge reasons why those two teams won rings. If you look at the charts, the Spurs do well when they improve their offense year-over-year without losing too much of the defensive end. This season, such an outcome is possible.
4. That 2004 team sure was a weird one. They were very good at defense but they were almost equally as bad on offense. Looking at the charts, it's not too surprising that the reason that team lost was due to an inability to score when it counted.
5. The 2008 and 2009 Spurs teams were pretty damn bad. Compared to the 2007 team, the Spurs lost huge ground on the defensive end and weren't as good offensively either. By comparison, this year's team at least seems headed back in the right direction.
Caveats
A. The Spurs are undeniably fragile. Duncan broke down last season. Ginobili has broken down the last two seasons. If the Spurs lose the battle against the injury bug, the numbers can quickly start heading the wrong way.
B. The schedule has been extremely easy so far. In fact,
Jeff Sagarin's schedule rating system indicates that the Spurs have played the second easiest schedule in the entire NBA. They've played 20 home games to only 13 road games -- and most of the contests have been against bad teams. This is important to note because the surge the Spurs usually experience in the second half of the season may be negated by the tougher schedule. If that happens, the theoretically improvements in the above stats may not occur.
Bottomline
Despite the rugged start and the uneven play, there is legit reason to honestly say number five is possible. The road will be treacherous and the obstacles will be many, however the current status of the Spurs is one containing silver linings aplenty.
Believe.
