"Shots just went in, and coach kept calling my number," Jackson said after shooting 8 for 12 from the field, including 3 for 4 on 3-pointers. "(Dallas) just kept having coverages where they really didn't come off our wings, nor did they want to leave Andre (Drummond). I was just a recipient of the coverage they played."
It was Jackson's first 20-point game since he had 24 at Miami on Jan. 28. He reached double digits just four times in nine games since, averaging 8.9 points during that stretch.
"I thought he played well tonight, and we needed it," Pistons coach Stan Van Gundy said.
Jackson had 12 of his points in the first half, when the Pistons roared out to a 62-35 lead.
"We had no energy," Dallas center Dirk Nowitzki said, "no bounce about ourselves. It was one of the worst halves we've played all season, and you could tell in the second we had a lot more bounce."
Nowitzki led the way in the third quarter, scoring 13 of his game-high 24 points, to help the Mavericks rally.
"We burned the first half at halftime," Dallas coach Rick Carlisle said. "The second half has got to be the norm for us. The first half was an embarrassment, and we all know it and we all own it. It cost us the game, it's pretty clear."
Dallas pulled within eight midway through the fourth quarter, but the Pistons held them off the rest of the way until Deron Williams hit s 3-pointer in the final seconds to provide the final score. Nowitzki also had 10 rebounds. Harrison Barnes added 16 points, Seth Curry had 13 and Williams 12.
The Pistons never trailed, taking a 10-0 lead to start the game, making 52.1 percent of their shots in the first half. However, Dallas outscored Detroit 56-36 in the second half.
