Per Eric Koreen of The Athletic, DeRozan said it felt like the Raptors "were playing 5-on-8" against the Warriors and referees.
Many in the Raptors locker room shared their frustration with the officiating.
Per Tim Bontemps of the Washington Post, Toronto head coach Dwane Casey joked maybe the refs "didn't think we deserved [to win] after that first half" after saying he had tremendous respect for their job.
DeRozan, who scored a game-high 42 points, nearly led the Raptors to a stunning comeback against the defending NBA champions. After trailing by 27 points at halftime, Toronto outscored the Warriors 71-46 in the second half.
There wasn't an unusual disparity in fouls called between the two teams. The Raptors were whistled for 23 fouls, compared to 20 for the Warriors, but Toronto actually attempted more free throws (32-28).
