A 14-2 run gave the Nets a 19-8 lead, and when Orlando got within seven late in the first quarter, Brooklyn scored the final 11 points, highlighted by C.J. Watson's six points in 4 seconds.
He made a 3-pointer, then stole the inbounds pass and drew a foul while making a layup. Reggie Evans' free throws made it 35-17 headed to the second and the rout seemed on, even if the Nets weren't buying it.
"Like we've been talking about, it's tough to beat a team when you play them two games in a row," Humphries said. "You have a big win, they're motivated to come in here and play. So we knew they were going to make a run, but we were able to handle it and finish the game out."
It was hardly a run. Orlando crawled back into it, with some help from the Nets.
Andray Blatche's basket to open the second made it a 20-point game, but Afflalo had a pair of three-point plays in a 12-2 surge that cut the lead in half. Brooklyn recovered and went into the half leading 50-35.
The Magic then outscored the Nets 18-13 in a tough-to-watch third quarter in which the teams combined to shoot 12 for 34, and cut it all the way to 75-70 on Davis' basket with 2:07 remaining in the game.
Williams answered with a jumper, and after another basket by Davis, he found Lopez inside for a 79-72 advantage with 59 seconds to play. He added a free throw to push it to eight and the Nets were safe from there.
Orlando finished 1 of 12 from 3-point range.
