Jae Crowder scored 16 points as five Celtics reached double figures. The Bulls didn't trail in the second half, using a 10-0 scoring run - which included eight points from Wade - to build a 19-point lead in the fourth quarter on the way to the convincing win.
The Bulls and Celtics don't square off again until Friday, but here's three takeaways from Game 2 to tide you over until then.

After Jimmy Butler hit a jumper in the lane over Marcus Smart in the second quarter one Celtics fan in the crowd, who identified himself as Mike S. from Everett, turned to his friend and said, "Why didn't we trade for Jimmy?" Butler also posted eight rebounds and eight assists. He scored 20 points but was just 6 of 15 from the floor, including 1 of 5 from 3-point range.
"We don't have home-court advantage, so we had to get one here if we want to win this series", Wade said.
