There are a couple of very different sets of numbers that caught my eye this morning.
First, is the postseason data from 82games.com , which shows that Rajon Rondo  was the Celtics  best player in the playoffs last season, and by a fairly wide margin. There are a couple of other observations we can make from the data. Among them:
1. The Celtics  really missed Kevin Garnett . Compare the 2008-09 playoff numbers with the 2007-08 numbers  and not only will Garnett’s Roland Rating (a simple explanation is here ) jump right off the page, but so will the effect he had on his teammates …
2. Particularly Paul Pierce . The Captain shot much worse in 2008-09  then in 2007-08  and had a significantly lower percentage of assists leading to his shots, which speaks to ball movement, which is one of Garnett’s most underrated offensive contributions. There were a number of theories for Pierce’s sub-par postseason, but a simple reason may have been that he just had to do too much and work too hard to get his shot off without KG.
3. The bench was really bad, especially Stephon Marbury . There was also no depth. Of the players who did play, Eddie House  was the biggest contributor among the reserves (no surprise), but that was about it.
Moving on, the fine fellows at basketball-reference.com have put up a huge amount of preseason data  (hat tip to Henry Abbott at True Hoop ), and from that we can see that the Celtics most efficient offensive player has been Mike Sweetney  (!)
We can also see that Garnett and Rasheed Wallace  have been killing it defensively. Of possibly greater importance, the Celtics have also played the best team defense in the NBA, which is nice. You can waste hours of your life playing with this stuff, but as Abbott and everyone else pointed out, there’s only a week left until the games start to really count, which is the best number of all.
