Though traditional stats will indicate that Curry is a very efficient scorer from his position, the advanced shooting stats give better insight into his shooting prowess.
First, let me define the stats of true shooting% (TS%) and effective field goal% (eFG%).
TS%: a measure of efficiency that takes into account free throws, 3-pointers, and field goals; formula is points/(2*(FGA + 0.44 FTA))
eFG%: a measure of efficiency that integrates the increased value of the 3 (a 3-pointer has 1.5 times the value of a 2-pointer)
Basically, these stats are a more effective way to gauge a player’s efficiency than just FG%.
Looking at Curry, he was top 8 in both stats in 2018-19 with a 64.1% TS and 60.4% eFG. The only guard ahead of him in both was Joe Harris, who doesn’t have nearly the volume or difficulty of Curry’s shots. The leader in both stats was Rudy Gobert, who of course just mostly takes shots within about 5 feet.
Curry was the most efficient high-volume scorer based off 2018-19 and has been among the best for years dating back to his MVP seasons. In his 2016 season, Curry led the league in TS% at 66.9 despite hoisting up a league-high 886 3s of various range and difficulty. He was also 2nd in eFG% at 63 behind only DeAndre Jordan.
Compared to other high-volume scorers, Steph is ahead of the competition in these efficiency stats despite sometimes having a lower FG%. The following comparison is from the 2015-16 season when Curry’s volume was highest:
Curry: 66.9 TS%, 63 eFG%
Durant: 63.4 TS%, 57.3 eFG%
Kawhi: 61.6 TS%, 56.5 TS%
Harden: 59.8 TS%, 51.2 eFG%
LeBron: 58.8 TS%, 55.1 eFG%
Lillard: 56 TS%, 49.7 eFG%
Considering the difficulty and volume of Curry’s shots, he deserves much more credit for this type of efficiency that he is putting up.
