We'll look at 3 calculations here to measure a player's ability to shoot:
When a player is on the court, how many shots does the player attempt compared the rest of the team?
A percentage of shots taken is measured by taking a players' field goal attempts divided by its percentage of minutes played multiplied by its team's field goal attempts.
%Shots = Player's FGA / (%Min * TeamFGA)
For example, Iowa's Jarrod Uthoff took 30.1% of his team's shots in 2015-2016 season. This ranked 50th amongst all Division-I players.
Uthoff attempted 487 of his team's 2027 shots and played in 78.2% minutes over the year.
%Shots = 487 / .782 x 2027 = 30.1
A percentage of shots a player has taken is a good indication of possessions used.
The exact calculation used for teams here is also applied to individuals. As a reminder, effective field goal percentage accounts for the fact that a 3-point field goal is worth more than a two-point field goal.
eFG% = (.5 * 3FGM + FGM) / FGA
For example, Oklahoma's Buddy Hield eFG% was 62.3% in the 2015-2016 season. This was 29th in the country.
147 of Hield's 301 made field goals were from behind 3-point line, and he attempted 601 total shots.
eFG% = (.5 * 147 + 301) / 601 = 0.632 * 100
True shooting percentage is used to more accurately define a player's ability to shoot. It incorporates field goal percentage, field goal attempts, and free throw attempts.
It uses the same multiplier (.475) that is used when calculating efficiency. The multiplier estimates how many free throw attempts equal one possession.
TS% = Points scored / ( 2* (FGA + 0.475 * FTA) )
For example, Duke's Marshall Plumlee posted a true shooting percentage of 66.2% in the 2015-2016 season. This is good for 12th in the country.
Plumlee scored 300 points, attempted 154 field goals and 153 free throws.
TS% = 300 / (2* 154 + 0.475*153) ) = 0.6617 * 100
