Smith had 18 points, a career-high 11 assists and five steals for Atlanta.

Jamal Crawford had 17 points and Horford added 15 for the Hawks.
Pistons coach John Kuester said the Hawks "know how to turn it on when they have to."
"It's always tough to come back when you're down by so much," Hamilton said. "The game is about runs, you know. And the run that they were in the first and second quarter, it's really hard to come back. You're fighting an uphill battle the whole game."
Hamilton wasn't comforted by Detroit's attempted comeback.
"I can't see any positives out of this game," he said. "We lost by 30, 20, whatever. I really can't see any positives out of this game."

Atlanta opened with assists on each of its 12 baskets in the first quarter and led 28-7 after an 18-1 run.
