NBA Referee Profile
Ron Olesiak
Ron Olesiak has worked 1,128 NBA games, and his foul numbers tell you exactly what kind of crew to expect when he's on the floor. His career average of 44.7 personal fouls per game runs 0.4% below league average — he lets play run. Free throw attempts follow the same pattern at 51.4 per game, sitting 1.5% under league norms. That combination means fewer stoppages, faster pace, and less free-throw volume to lean on in your totals calculus. Physical play tends to get swallowed. The more significant number for bettors is his home team win rate of 61.9%. League-wide home teams win at roughly 59-60%, and Olesiak sits above that. That's not a fluke — it's a lean that shows up over 1,128 games. When Olesiak is assigned, home-court advantage gets a quiet bump. Fade road underdogs harder, and don't count on the whistle to bail out a struggling away squad.
