Dewayne Dedmon matched his career high with 20 points and had 13 rebounds in his matchup with Andre Drummond, who had 25 points and 15 rebounds for Detroit. Dedmon’s three-point play gave Atlanta a 109-107 lead with 1:34 remaining. Blake Griffin had 23 points for Detroit. The Pistons blamed the loss on bad defense. “Tough to give up 118 and try to win on the road,” Griffin said. “Or win in general.”Drummond’s big game was not enough to overcome the defensive breakdowns, including in the closing minutes.
