A year ago, Hornet's Blog At The Hive and I both put up posts talking about Chris Paul, using what limited statistical measures exist to try and rate his defensive production. The measures weren't particularly encouraging, and Paul came out looking like he was a pretty weak defender, despite my arguments that he was likely just average.
At The Hive responded to my post with "Great stuff, Ryan. My dream is that on this same day next year, we can both put up posts describing how awesome his defense is."
Well, it's a year later. Let's see how it all shook out:
Last year there was a hue and cry about Chris Paul's defense when he was contending for the MVP prize, some of it based on the adjusted +/- stat that tries to isolate Paul's play from his teammates and seemed to indicate the team was better defensively without him. Last year the Adjusted +/- essentially said Paul's crazy offensive contributions were nearly canceled out by his defensive deficiencies as the Hornet's defensive efficiency was 5.6 points worse when he was on the floor.(i.e. for every 100 possessions the Hornets gave up 5 more points with him than without him)
It didn't stop there either. Another measurable way Paul's defense was poor last year was his inability to force bad shots. Point Guards playing against Paul had a eFG% of 52%, placing Paul in the bottom five among the league's point guards. He allowed opposing Point Guards to post a PER of 18.3, also in the bottom five of the league. He also allowed the 11th most number of shots, and was right in the middle of the pack in giving up assists. They were pretty grim numbers.
This year, however, Paul's defensive turnaround has been nothing short of amazing. And I mean it. I had to check the numbers twice before posting them here.
Adjusted +/- now ranks Paul as the 2nd best player in the league, and unlike last year, the Hornet's defensive efficiency improves by 3.1 with him on the floor, a total improvement of 8.7 points per 100 posessions. To put that in perspective, if you improved the worst defense in the league by 8.7 points per 100 posessions, they'd become the 6th best defense in the league.
So how did he do it? What has he improved to make his defensive so much more effective? Pretty much everything. Paul's defensive eFG% has improved from 52% to 47%, going from 26th to 13th in effective Field Goal defense. That's a big improvement, but it still didn't seem that great because it merely made him average. So I started looking at the other stats, and it became pretty obvious that while Paul may not force consistently bad shots, he controls opposing point guards like no other. Per 48 minutes, point guards facing the Hornets manage the 3rd fewest Field Goal Attempts, the 2nd fewest Points, the 2nd fewest Assists, and the 9th fewest free throws. As a result, point guards playing against the Hornets manage a PER of 14.8. In fact, the only thing Paul doesn't do well? Force opposing Point Guards into turnovers. Last year he was top 5. This year he is the 6th worst, forcing one less turnover per 48 minutes. That's a pretty amazing number, considering he still leads the league in steals, but it corresponds with the types of steals we see him make per game which are more reach-in steals on driving wings then pressure steals in the open court.
So has Paul become an awesome defender? Considering how disruptive he is on help defense, and how he has clearly improved his on the ball defense, I'd have to say yes. Sure, he can't bother tall wing players taking corner-threes when rotating because he's just too short, but I can live with that considering everything else he does.
Notes: For those of you interested, the numbers were collected from the Production by Position Team pages on 82games.com. Here's the Hornet's page. Yes, I know that those stats report the production of players designated by 82games as "point guards" and that team defense probably impacts the stats, and that it includes both Paul's defense against opposing point guards and that of his backups. However, if you want to argue that lead-footed Antonio Daniels and floor-bound Devin Brown provide A. A positive defensive impact, or B. Improve the defense tremendously in their 10 minutes per game at the point guard position, and that Paul still sucks, feel free . . . and expect derision.
Be sure to read Niall's breakdown of the Hornet's possible first round opponents. Good stuff!

I recall that last year one primary justification for CP's poor adjusted +/- was that it reflects the relative contribution of the bench just as much as it does CP's defensive ability. Doesn't the reverse apply this year? I don't need your fancy math to know that CP being off the floor means that our second string is ON the floor, and that our bench outscored the other team's about 3 times all year. So I'm very prepared to believe that his defense was improved this year, but we were also abysmal when he was off the court for reasons that don't have to do with missing his defense.

I dismissed the adjusted +/- last year for that reason, and because it was relying on a notoriously small sample size(the real problem with the system) to try and seperate Paul from his teammates.
It's why I never rely on +/- numbers and even more rarely quote them, and instead get into stats like the ones I followed that section with.

Opposing pg's also probably score and shoot less this year because we've been thinner up front, so they throw it into the bigs and wings down low because our guys have been injured.
Then again, I think it's laughable that people say CP is mediocre defensively. Either Bucher or Stein (on the last Bill Simmons podcast) compared him to AI in that they both gamble on steals and leave their teammates in bad position to defend when they miss the steal. Ummm, I don't know what they've been watching, but CP almost never misses on a gamble and when he rarely does, he recovers quickly

Fair enough. Do you happen to know how opposing PG's 3pt accuracy changes when they face CP? From watching the games, it seems like he is closing out on shooters a lot better this year, even though he hasn't gotten better at being tall. I don't know if he's being more conservative about poaching off his man when the ball is on the other side of the court, or if he's just getting smarter or more determined about recovering when the ball is swung back to his man.

I agree with bigindian that when CP "gambles" (by lagging off his man into passing lanes) he is so smart about it that even when he doesn't get the steal he rarely leaves his man uncovered for long. I also think that his teammates are pretty alert about switching, which is a smart way to get the most out of a disruptive ball-hawk like Chris. The trouble is with teams that swing the ball aggresively to punish the switching and find the open shooter on the far side of the court.

@ otherMark: Go tell Chris Paul that he can't get better at being tall and watch him report to training camp at 6-4 next season!
Great job crunching the numbers for this, Ryan. Just from my own observations, I'd say CP has gotten smarter about his gambles over the course of this season. Remember back in the early months he was getting burned by the likes of Derek Fisher and Chris Quinn? He often went wandering and left them wide open behind the arc. But I can't recall any point guard killing us from deep in recent months.
Good point by bigindian though about teams looking to score inside against us more this season.

I've also heard the theory that with Pargo gone and Byron only rarely running the two-point guard sets, CP no longer has to guard opposing shooting guards as he did last year when Pargo was on the floor with him. Thus the bad defensive numbers of 07-08 were more a result of Chris having to guard out of position and the good defensive numbers this year result from Chris no longer having to do that and being able to concentrate on defending guys his own size (roughly). Seems plausible enough....

AS you evaluate defensive players one must consider " blowbyes" and "pickup points" On the ball defense and the result. Was the defense by design ( force a player into help therefore giving up space early in the posession ?
Did a " blowbye " take place and was there a POTENTIAL assist ( the open shooter misses the shot off a great pass)
How often are scores made on the baseline due to othe 'blowbye" forcing the bigs to help ? ( i call these red flags)
And "pickup pts" where on the floor and flowing into what type of defense ( zone or man or into traps ? Sometimes to give the impression your beat to forece certain guards into " tempting but risky situations.
Point being there are so many ways to approach and research players. Thats what makes it fun ( I wish they would redefine the assist rule) have different levels of value.
Paul is a terrific "off the ball defender" The quick jet like pt guards can get into the lane. When the lateral quicks and length of the Hornets improves itself Pauls will be even more lethal since he knows how to create defensive angles.
You posted some nice stuff. I enjoyed the read..

CP3 has had another MVP year unfort the other members of the team haven't followed up last year with great seasons
West is off/on
TC has been basically a waste and I have heard rumors he loafed all off-season
