By far the best among relatively easy ways to grade and rank offenses and defenses is to use efficiency, which is the number of points scored (offense) per 100 possessions, or the number of points allowed (defense) per 100 possessions. This is the scoring rate, so differences in pace (how fast teams choose to play) are washed out (corrected for).
You can not simply use points per game because this makes the offense of fast pace teams look better than it is and the defense of fast paced teams look worse than it is. And the reverse would be true for slow paced teams.
The fact that there are more than 6,000 offensive and defensive possessions for NBA teams during a regular season means that even tiny differences in efficiency are significant and have a real world impact. Even if there is just a 0.1 difference between two teams, it is still valid to say that the higher team had the better offense or defense. A difference of 2 points is actually a fairly major difference, and in real life will often mean the difference between a team that has a possibility of winning a Championship and a team that does not.
Yes, I'm giving you a hard stare right now, Denver, laugh out loud. You were good but you were not Championship material this season, and your defense was, when all was said and done, overrated.

The Portland Trailblazers were the best NBA team this year if you look only at offense. The Phoenix Suns were very close behind. The Los Angeles Lakers and the Cleveland Cavaliers trailed those top two offenses by a small amount.
Remember, do not be fooled by the seemingly small differences, because remember we are talking about the rate of scoring across more than 6,000 possessions of the ball. This is a huge statistical sample, so even seemingly extremely small differences are significant in the real world.
So the Dallas Mavericks, the Boston Celtics, and the Denver Nuggets (5th, 6th, and 7th, respectively) were good offenses but they were clearly not as good as the top four.
The Utah Jazz had the 8th best offense.
Rounding out the top ten were those perennial runner-gunners the Golden State Warriors (9th) and the much slower paced Atanta Hawks (10th); these two were slightly less offensively powerful than the Utah Jazz.
The Orlando Magic finished outside of the top 10 by the slimmest of margins.
We are only specifically mentioning the top 10 and the bottom three. For the middle and lower tiers, see the list.
The worst offensive teams in the NBA in 2008-09, in order from really bad to worst of all, were the Memphis Grizzlies (28th) the Oklahoma Thunder (29th) and the Los Angeles Clippers (30th) Happy lottery to those squads.

The best defense in the NBA in 2008-09 was by the Orlando Magic, who had a little better defense than did the Boston Celtics and the Clevaland Cavaliers, who were extremely close behind Boston as the 3rd best defense.
After a fairly large gap, you come to the next tier of defensive teams, which were the Rockets in 4th, the Spurs in 5th, and the Lakers in 6th.
After another substantial drop off, the Charlotte Bobcats were the 7th best defensive team in the NBA this year.
After a small but meaningful additional drop off, the Denver Nuggets were the 8th best defensive team, and they were followed closely by the Hornets (9th) and the Jazz (10th).
We are only specifically mentioning the top 10 and the bottom three. For the middle and lower tiers, see the list.
The worst defensive teams in the NBA in the 2008-09 season, going from really bad to the very worst defense of all, were the Golden State Warriors (28th) the Washington Wizards (29th) and the Sacramento Kings (30th). Happy lottery to those squads.
Note that the three worst offenses were completely different from the three worst defenses; no team had one of the three worst offenses and one of the three worst defenses at the same time!
Thank goodness for that, right?
