Pretty much all of the efficiency metrics revolve around shot attempts - FG%, eFG%, TS% etc. Each has their weak points and none take into account the value of all three of the different shot values - 2pt, 3pt & FT while only TS% takes into account the actual points scored by the player. It also includes a somewhat arbitrary multiplier for free throw attempts.
Why do we not measure the efficiency of a player based on points only? So basically, the amount of points a player attempts vs the amount of points he eventually scores. To me, the two metrics reflect the difference between great scorers and great shooters, they are not always directly proportional.
Example, a player attempts 10 two pointers, 5 three pointers and 5 free throws per game throughout a season. He ends up averaging 5 made twos, 2 made threes and 4.5 made free throws. The total points he attempted was:
(10 x 2) + (5 x 3) + 5 = 40 points
He succeeds in scoring:
(5 x 2) + (2 x 3) + 4.5 = 20.5ppg
His scoring efficiency is therefore:
20.5/40 = 51.25%
His shooting efficiency, based on TS% is:
20.5/((15 x 2) + (4.5 x 0.88)) = 60.36%
Applying scoring efficiency (ScEff) to some all time great scorers/shooters:
Michael Jordan -
TS% - 56.9%
ScEff - 54.1%
LeBron James -
TS% - 58.8%
ScEff - 52.6%
Steph Curry -
TS% - 62.8%
ScEff - 50.7%
Larry Bird -
TS% - 56.4%
ScEff - 53.4%
Kobe -
TS% - 55.0%
ScEff - 49.7%
Harden -
TS% - 61.0%
ScEff - 50.3%
Wilt -
TS% - 54.7%
ScEff - 53.4%
Interestingly, Jordan moves from the 4th best TS% of that 7 player group, to 1st place in terms of scoring efficiency. Curry goes from 1st to 5th. Jordan is widely regarded as the greatest scorer of all time and Curry as the greatest shooter of all time. Kind of apt that they would swap places on these lists.
TLDR first year econ student trying to be smart
Missed shots are all worth 0 points. Why would it be better to miss a 2 than a 3? That’s what your stat suggests.
Because a missed 3 is not 50% worse than a missed 2. It’s very close to equal.
Either way you bricked a shot and now the other team will rebound it, or your team might rebound it.
Your stat views Curry missing a 3 as a heinous crime.
Thanks for explaining it in a way that doesn’t make you look like a complete douchebag like everybody else in this thread…
A missed three is worth the same as a missed 2. A made three is worth more than a made 2. That’s why.
You’re under weighting 3pointers. They still only take FGA. They shouldn’t cost more in the efficiency equation.
You realize you just made a less useful version of true shooting, right
Lololol just loving this dumb metric getting dunked on in the comments
If that’s what you get joy out of then you’re a miserable person…
I thought you were going to do points per shot and instead came up with this monstrosity.
So by your metric, a player who attempts 10 3’s a game and makes 5 would be at 50%, but a player who attempts 10 2’s and makes 5 would also be at 50%? So they’re both equally “efficient”, yet one is scoring 5 more points a game.
because 3>2
/thread
I thought you were going to make a valid point about how 10 ppg on 60% TS should be wright differently than 30 ppg on 60% TS but instead we got this nonsense.
Based on your metric, someone who scores 41% at the rim is more efficient than someone who scores 40% from 3. I cannot stress enough how braindead a take that is.
Just explain something to somebody without being a douchebag…it’s not hard.
The better TS% should the be the points/(FGA + non-and-one fouls you shot FT for)
Hey man, don’t try and reinvent the wheel. Especially if your invention is a steaming pile of garbage.
How about responding to someone like a civlised human being instead of a miserable, arrogant prick?
Nah.
Well we sure know why you aren’t an analyst
