Richardson scored 28 points, Davis added 15 and the backcourt duo combined for 17 in the third period as the Golden State Warriors rallied to rout the Hawks, 122-97, in the season opener for both teams.

NBA TV highlights from Hawks-Warriors: Play

Atlanta, which had a league-worst 13-69 mark last season, held a 57-47 lead at the break and a 65-55 advantage almost four minutes into the third quarter before everything fell apart as Golden State scored 27 of the next 29 points to take control.

"You've got to give them credit because they got after us in the third quarter and we kind of went the other way a little bit," Hawks coach Mike Woodson said. "They were the aggressor. Normally, when you play in this league, the team that is the aggressive team is going to get calls and they became the aggressor in the third. They got a lot of calls, they went to the line a lot and we just settled."

The crowd of 18,629 booed the home team early for its lackluster play but were giving a standing ovation by the end of the period after the surge.

"Who cares about some boos," Davis said. "We know what we've got to do. I told the fellas at halftime, the one thing we're not going to do is play to the crowd, especially if they're booing us. We've got to come and play our basketball and when we start playing, they'll start cheering and that's what's happened."

The Warriors outscored the Hawks, 39-16, in the period en route to their seventh straight win against Atlanta -- Golden State's longest streak against any team.

"We did what we needed to do," Warriors coach Mike Montgomery said. "We're still learning about ourselves and what you saw in the second half is how we have to play."

Richardson scored eight points in the third quarter and Davis tallied nine before the oft-injured guard departed with a strained left hamstring with 3:53 left in the period.

"It was just little things we were doing, not rebounding, turning the ball over a lot, first game jitters," said Richardson of the lackluster first half. "We came back in the second half a better team. We picked up our defensive intensity. I think that was a big part of why we came back with a better second half."

Davis hopes to be able to play on Friday against Utah.

"I think it was just a tweak and fortunately we were ahead far enough in the game where it was no sense really to put him back in," said Warriors guard Derek Fisher, who scored seven of his 12 points in the third. "I'm sure our trainers will make some type of statement tomorrow, but Baron's a gamer and I'm sure he'll figure out a way to go Friday night for sure."

Mickael Pietrus scored eight points during the surge and finished with 20 points off the bench. Troy Murphy added 19 points and nine rebounds for the Warriors.

Offseason acquisition Joe Johnson, who is being paid $70 million over the next five years by Atlanta, scored nine points in the first quarter but did not score again until the final period, finishing with 17 points.

"I got into foul trouble and then it was kind of hard for me to get back in the flow of the game," Johnson said. "It was tough but it's part of the game, it happens."

Al Harrington collected 18 points, nine rebounds, five assists and three steals for Atlanta, which also got 13 points and 12 rebounds from Zaza Pachulia.
