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, South Carolina's Sindarius Thornwell's free throw rate was 59.9 in the 2016-2017 season. This ranked 75th amongst all Division-I players.
Thornwell attempted 259 free throws and 438 field goals.
FTRate = 100 * 259 / 438 = 59.9
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, London Perrantes of Virginia committed 1.21 fouls per 40 minutes in 2016-2017. This was 4th in the country.
Perrantes committed 33 fouls playing in 1093 minutes over the season.
FC/40 = (33 / 1093) * 40 = 1.21
Applying all of these assumptions can give a fair estimate of a player's fouls drawn.
For example, Nick Ward of Michigan State drew 8.8 fouls per 40 minutes played in 2016-2017. This ranked 1st in the nation.
Ward played in 694 minutes in the 2016-2017 season drawing about 153 fouls.
FD/40 = (153 / 694) * 40 = 8.8
