There are 3 metrics that indicate how fouls factor into an individual’s effectiveness:
Free throw rate measures a player’s ability to get to the foul line relative to how often he attempts to score. It takes a players free throw attempts and divides those attempts by the player’s total field goal attempts.
FTRate = 100 * FTA / FGA
For example, Steffon Mitchell of Boston College had a free throw rate was 147.9 in the 2018-2019 season. This ranked 1st amongst all Division-I players.
Mitchell attempted 108 free throws and 73 field goals.
FTRate = 100 * 108 / 73 = 147.9
This is a straight-forward stat that shows the amount of fouls a player commits per 40 minutes played.
FC/40 = (Fouls committed / MP) * 40
For example, Kyle Guy of Virginia committed 1.16 fouls per 40 minutes in 2018-2019. This was 5th in the country.
Snider committed 39 fouls playing in 1345 minutes over the season.
FC/40 = (39 / 1345) * 40 = 1.16
Applying all of these assumptions can give a fair estimate of a player’s fouls drawn.
For example, Deishuan Booker of Long Beach State drew 7.6 fouls per 40 minutes played in 2018-2019. This ranked 1st in the nation.
Booker played in 1060 minutes in the 2018-2019 season drawing about 200 fouls.
FD/40 = (200 / 987) * 40 = 7.6
