"It was fun," said Hayward, who was coming off a season-high 35 points Wednesday night in a victory over Minnesota. "I think when we have good spacing, we have talented players and it just makes the game easier. If you make the right read, everybody gets involved and it's fun."
Jaylen Brown scored 21 points, Jayson Tatum added 18 points, and Al Horford had 10 points, eight rebounds and eight assists.
The Celtics won easily despite playing their second straight game with star guard Kyrie Irving sidelined by scratched corneas. Without Irving, the Celtics moved the ball around and had 35 assists on 42 field goals.
Hayward and Horford had eight apiece and Terry Rozier, who started for Irving, added seven assists for the Celtics.
"We've really tried to emphasize that all year," coach Brad Stevens said. "For the most part everybody was in a good rhythm and playing well together and seeking out the right shot. We've just got to keep doing that as much as possible."
