There are 3 metrics that indicate how fouls factor into an individual's effectiveness:
Free Throw Rate (FTRate)
Fouls committed per 40 minutes played (FC/40)
Fouls drawn per 40 minutes played (FD/40)
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, Duke's Marshall Plumlee's free throw rate was 99.3 in 2015-2016. This ranked 3rd amongst all Division-I players.
Plumlee attempted 153 free throws and 154 field goals.
FTRate = 100 * 153 / 154 = 99.3
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, Bryce Alford of UCLA committed 1.4 fouls per 40 minutes in 2015-2016. This was 18th in the country.
Alford committed 41 fouls playing in 1159 minutes over the season.
FC/40 = (41 / 1159) * 40 = 1.4
Applying all of these assumptions can give a fair estimate of a player's fouls drawn.
For example, Cal's Jaylen Brown drew 7 fouls per 40 minutes played in 2015-2016. This ranked 30th in the nation.
Brown played in 959 minutes in 2015-2016 drawing about 166 fouls.
FD/40 = (166 / 959) * 40 = 6.88
