Caron Butler's Explosion

12 Dec 2007 01:30 pm

During the offseason, John Hollinger's Caron Butler forecast argued that "Although his trend line says the jumper is becoming more of a weapon each year, I'm not sure Butler can keep stroking those 20 footers at quite the clip he did last season." I'm not sure I understand why Hollinger chose to go against his own projections formula, which saw Butler's field goal percentage going up, but as you can see above, Hollinger was dead wrong. Butler's shot's become more accurate and his true shooting percentage has skyrocketed to above Kobe Bryant or LeBron James.

It's tempting, in a narrative sense, to attribute Butler's emergence to the Gilbert Arenas injury that it's done a lot to offset. The reality, though, seems to be simply that Butler's learned to shoot from beyond the three point arc. As you can see, his percentage on the longball was formerly in the "he really can't hit that shot" range and now he's a good three point shooter. The move from average 1.1 treys per game and making 25 percent of them, to hitting 47 percent of 2.5 per game is worth substantial scoring efficiency on its own terms. And, of course, the ability to hit that shot opens up other aspects of your offensive game.

In my view, he's probably playing better this season than Arenas was last year, but even with Gilbert injured he's still the clear focal point of the Wizards' marketing and the branding inside the Verizon Center.

what the hell is TS%?

It's a measure of shooting efficiency that accounts for the greater points awarded for a three point shot. So (I think) a 33% three point shooter is equivalent to a 50% two point shooter.

Man, you write about whatever Petey tells you to, don't you?

TS% is "true shooting percentage." It adjusts for the greater value of the 3-point shot, so it's a better gauge of shooting accuracy than plain old FG%.

So I wasn't quite right, as it accounts for foul shots as well, apparently:

TS% True Shooting Percentage calculates what a player’s shooting percentage would be if we accounted for free throws and 3-pointers. True Shooting Percentage = (Total points x 50) divided by [(FGA + (FTA x 0.44)]

Someone send this URL to Kobe. I miss his rage.

Don't worry: there are plenty of Laker's fans around here feeling it right now.

The marketing focus is on Gilbert because marketing is based on scoring average - points per game - rather than the other factors that real basketball fans know are important (like shooting percentage). And Caron's 22 PPG is good, but not great. The fact that he's shooting such a high percentage, coupled with his defense, etc., is what makes him such a great player this year.

It's highly unlikely that Butler will keep up his 3 point shooting pace; his current rate of 47% would have been second best in the league last year. If he does, he'll be statistically almost as good as Arenas was last year (Butler's current PER is around 23, while Arenas had PER of 24 for all of last season). Even then, I think Arenas's ability to dominate games and make clutch shots would mark him as the better player. Butler is more consistent though....

More math, but the same point RC makes (regression to the mean) can be found here:

APBR is actually a great resource for all of these issues that Matt occasionally mucks up in his love for pretty graphs ;)

The bottom line is that Caron is almost certainly not as good a three point shooter as his first 50 3PA would indicate...

Scoring average matters, not just shooting percentage. A high-volume shooter who maintains an OK shooting percentage is probably creating his own shot in difficult situations and drawing the defense away from others. A high-percentage, low-volume shooter could just be taking advantage of the occasional open shot.

That's not the case with Butler, who is taking on a solid portion of the team's scoring load. But he's still not quite up there with the league's offensive elite.

Matt, your graphs need help.

Your vertical scale has tick marks at values that make it very difficult to interpolate between the tick marks.

For example, last year Butler's 3P% was about halfway between .350 and .175. That math is not hard to do, it becomes harder if you look at 2004-5 where his 3P% is 2/3rds of the way from .175 to .350.

This would be much easier if your tick marks were at multiples of .200 (for example).

butler still seems to have come out of relatively nowhere as the third prong of DC's big three. e.g., i don't think many would have guessed that butler would be a serious improvement over hughes.

"Man, you write about whatever Petey tells you to, don't you?"

Someone's gotta run Matt's assignment desk. Who better than me?

"(TS%) accounts for foul shots as well, apparently"

Yup. Which is why it correctly accounts for how efficient you are in scoring.

Iverson, for example, who is only shooting 46% from the field and not particularly well from the 3pt line, has a TS% of 57% because he gets to the stripe early and often.

Here is a sorted list of NBA players by their TS% this year.

Could you label these things for us non-sporting folk, please, so we don't have to read a few lines to figure out we don't want to read it? I had no idea what this post was about till I got well into the first paragraph. Now I gather it's about some sport or other, and I'm sorry I wasted my time.

A nice big red "WARNING!!! SPORT POST!!! WARNING!!!" would be good.

"Scoring average matters, not just shooting percentage ... A high-percentage, low-volume shooter could just be taking advantage of the occasional open shot ... That's not the case with Butler, who is taking on a solid portion of the team's scoring load. But he's still not quite up there with the league's offensive elite."

Number of players in the association this year with a higher TS% than Butler and a higher Points per Minute average than Butler: 4

Amare Stoudemire
Dwight Howard
Manu Ginobili
Carlos Boozer

I'd say Caron is up there with the league's offensive elite so far.

Matt, your graphs need help.

I'm guessing here, but they all kind of look like they come from the PowerPoint automatic graphing feature, which often generates weird axes like the one you're complaining about.

as a technical matter, i appreciate that people like the "traditional-sounding" outcome of "true shooting percentage," but good old points-per-shot-attempt tells you the same thing (in terms of judging offensive efficiency) and has the advantage of being a number you can calculate in your head.

but no matter how you analyze it, butler is having an excellent first quarter of the season....

"good old points-per-shot-attempt tells you the same thing (in terms of judging offensive efficiency) and has the advantage of being a number you can calculate in your head."

How do you compute points-per-shot-attempt, and why is it any easier to compute in your head than TS%?

(Being an Iverson fan for a while now, I long ago learned how to compute TS% in my head so I could figure out if a 6-15 FG 11-13 FT boxscore line was a good performance or not...)

Personally, I'm astounded that the NBA still doesn't do TS% in its boxscores.

"How do you compute points-per-shot-attempt, and why is it any easier to compute in your head than TS%?"

I mean, if I understand correctly, the only step you save is dividing by 2 at the end, not a particularly difficult computation to do in your head...
