NBA Referee Profile
Matt Kallio
Matt Kallio has worked 175 NBA games and his foul numbers tell a clear story. At 38.2 personal fouls per game, he sits 1.0% below the league average — he lets play run. Teams that push pace and prefer fewer stoppages get a friendlier environment under Kallio than under most crews. Free throw attempts average 45 per game, essentially dead even with league norms at just 0.2% above average, meaning the low foul rate isn't translating into a dramatically suppressed trip to the line — fouls are called more selectively, not just swallowed entirely. The number that should stop bettors cold is his home team win rate: 56.6%. The league baseline for home wins hovers around 55%, and Kallio runs 1.6 points above that. It's not a massive lean, but it's consistent enough to factor in when a line feels razor-thin and the home side is already getting value.
