NBA Referee Profile
Derek Richardson
Derek Richardson has officiated 1,540 NBA games, and his foul-calling tendencies carry real implications for how you build a betting line around his assignments. Richardson reads a tight game — his career average of 42.8 personal fouls per game runs 1.7% above league average, and his 49 free throw attempts per game sits 1.9% above the norm. Those aren't massive deviations, but they're consistent enough to push totals and prop lines at the margin, particularly in games where pace and foul trouble are already factors. The more significant number is his home team win rate: 58.3%. The league baseline for home winning percentage hovers around 57-58%, so Richardson doesn't represent a dramatic lean, but he's consistently at the high end of that range. He's not a ref who suppresses the home crowd effect — if anything, he reflects it. Factor his assignments into home-favorite situations where the line feels tight.
