From Comcast SportsNetSAN FRANCISCO (AP) -- The San Francisco 49ers stymied 2011 NFL MVP Aaron Rodgers in Week 1, then record-setting Matthew Stafford in Week 2.This stingy, opportunistic defense is again making its mark as one of the league's best facing the top offenses and most prolific passers -- and that you can shake on.The Niners denied Stafford another milestone, Vernon Davis caught touchdown passes of 21 and 23 yards from Alex Smith, and San Francisco beat the Detroit Lions 27-19 on Sunday night in a September showdown of NFC powers that hardly lived up to its hype.Smith completed 20 of 31 throws for 226 yards and extended his franchise-record streak of passes without an interception to 216. He led the reigning NFC West champion Niners (2-0) to their ninth straight win in the series since the Lions' last victory on Sept. 25, 1995. Smith took a hard hand to the helmet from John Wendling late and bloodied his nose.The 49ers ran their home winning streak against the Lions to 12 games since Detroit's last victory at Candlestick Park on Nov. 2, 1975.And no heated greeting after this one. Coaches Jim Harbaugh and Jim Schwartz met each other with a friendly hello and handshake during pregame warmups, then an uneventful shake and half-hug when time expired.Frank Gore carried 17 times for 89 yards and a 1-yard touchdown, just missing his fifth 100-yard game in as many career meetings with the Lions.Calvin Johnson caught eight passes for 94 yards, but that was hardly enough as the Lions (1-1) never got closer than the 20 until their final drive on a cool, windy night by the bay. San Francisco's secondary kept Megatron from catching a touchdown pass for the second straight matchup, forcing Stafford to rely heavily on the running game.Another impressive outing by a defense that shut down Rodgers in a 30-22 win over the Packers last week at Lambeau Field.Stafford finished 19 for 32 with 230 yards, one touchdown and an interception, missing a chance to become the first player in NFL history to throw for 350 yards in five straight games. Drew Brees of the Saints also did so in four consecutive games last season.Stafford threw for 355 yards in last week's 27-23 win over St. Louis at home but also had three interceptions before halftime for the first time -- and said he couldn't do that again for the Lions to win. He never got in sync.The 49ers dominated on both sides of the ball 11 months to the day after rallying for a 25-19 win at Ford Field to hand Detroit its first defeat following a 5-0 start. It ended with excitable Harbaugh's firm handshake and backslap that ignited Lions coach Schwartz -- and they had to be separated leaving the field.There were some hot tempers Sunday, too. After Davis and Delanie Walker drove Cliff Avril to the sideline while blocking on a running play, Avril kicked Walker in the helmet. Lions right tackle Gosder Cherilus and 49ers cornerback Tarell Brown pushed and shoved after a big hit by Patrick Willis on Johnson in the first quarter.Smith exploited Detroit's depleted, frustrated secondary at every opportunity. On his TD, Davis easily beat Wendling, starting as regular safety Louis Delmas recovers from knee surgery.Smith hit Michael Crabtree on the left sideline for a 17-yard gain, then Davis scored on the next play. The Lions were without rookie cornerback Bill Bentley because of a concussion sustained last week and cornerback Chris Houston with an ankle injury.David Akers kicked field goals from 36 and 48 yards for San Francisco a week after connecting from 63 yards to tie an NFL record.Jason Hanson finished with field goals of 38, 41, 40 and 48 yards. He also missed one off the right upright on a 40-yard attempt late in the second quarter. The Lions scored their lone touchdown on Stafford's 9-yard TD pass to Brandon Pettigrew with 1:29 remaining.The 49ers ended their streak of 26 quarters spanning six straight regular-season games without a turnover, and 36 consecutive quarters without a lost fumble since Davis lost one Nov. 6 last year at Washington. San Francisco was trying to match the 2010 Patriots for the NFL record of seven games without a turnover.After Hanson's first field goal, Kendall Hunter fumbled the kickoff return after being stripped by Tahir Whitehead and Kassim Osgood recovered. It marked the first career lost fumble in 18 games for the second-year halfback.But Ahmad Brooks batted down a pass on third down in the ensuing series as the Lions had to settle for another field goal.San Francisco's defense delivered again on Detroit's next series. On third-and-6 from the 20, Stafford threw down the middle of the field with nobody even close and safety Dashon Goldson jumped in for an interception.A special teams blunder hurt the Lions late in the first quarter when Drayton Florence, another fill-in cornerback, was flagged for running into Akers. That gave the Niners first down at the 12, and Gore scored three plays later 3 seconds into the second quarter.San Francisco's defense kept Detroit out of the end zone on the Lions' first drive despite a big penalty. Chris Culliver received a debated pass interference from the replacement officials when he tipped a pass intended for Titus Young for a 33-yard penalty.
In case you missed it, the Warriors' season opener did not go well.
Final score: San Antonio 129, Golden State 100.
"That was a rough one," Warriors GM Bob Myers said on 95.7 The Game on Wednesday afternoon. "It's hard to evaluate. And I don't want to be critical of the players -- we're all part of it -- but I think effort stands out. I think we were out-competed a little bit. I don't think anybody is gonna run from that statement.
"As you watch any sports event, there are plays that shift the momentum of a game, where it seemed like we were trying to get back in it. And every time we would, they would hit a shot to kind of break our back again, or we would turn it over or there would be a rebound we didn't grab. Some of it is effort, some of it's being ready to play, and then some of it's the Spurs.
"They're good. They don't beat themselves. They never have. You have to beat them ... they earned it, we didn't. And if you wanted a wakeup call, that is about as good of a one as you can get."
The Spurs won the rebounding battle 55-35. They turned 21 offensive rebounds into 26 second-chance points.
San Antonio won the turnover battle (13 to 16), scored more fast break points (24 to 20) and shot eight more free throws (26 to 18) than the Warriors.
Golden State certainly did not look like the overwhelming favorite to win the title, but Myers understands that the team is a work in progress.
"This is the analogy that I think fits the best for me -- may not fit for you guys or the players -- you spend the last 9-10 months trying to climb a mountain, and you're there. You can see it. And you're at the summit, and you can actually see the pole; you can see the flag. And then someone tells you you gotta go back down. And you say, 'Come on, man. It's right there. Can't I just take these last few steps?' And they say it's closed, you gotta go home.
"So we walk down, you spend the whole offseason and you're off that mountain. And now somebody says, 'All right. Let's go.' Those first few steps, sometimes you're not looking at the feet in front of you. You're looking at the top of the mountain and you're thinking, 'Man. I gotta get all the way back up there.' You can't do it that way. You can't look at the top. You have to look at one foot in front of the other.
"And I think some of that will have to be overcome by us -- a team that went to the Finals two years in a row -- recognizing that this is the NBA; you have to play hard; every game does matter; you have to get better. But I think that game last night -- I hope, I think -- reminded our players of that. You can't talk about the playoffs right now. You gotta talk about the regular season. You gotta talk about Friday night in New Orleans."
LOS ANGELES -- Jordan Clarkson scored 12 of his 25 points in the fourth quarter, and the Los Angeles Lakers won coach Luke Walton's debut, holding off the Houston Rockets 120-114 on Wednesday night.
D'Angelo Russell scored 20 points and Julius Randle added 18 points, seven rebounds and six assists for the young Lakers, who got off to an exciting start in the franchise's first season without Kobe Bryant since 1995.
With a revamped roster coming off the worst season in the 16-time champion team's history, Los Angeles surged in the fourth quarter of an auspicious opener under Walton, the 36-year-old former Lakers forward.
James Harden had 34 points, a career-high 17 assists and eight rebounds for the Rockets, who lost in former Lakers coach Mike D'Antoni's debut on the Houston bench.
The Lakers played an up-tempo, aggressive offensive game under Walton, and nobody seized the moment better than Clarkson, who came off the bench in his first game since signing a $50 million contract. His 3-pointer put the Lakers up 116-112 with 1:48 left, and the Lakers hung on while the Rockets missed a long series of open shots in the final minute.
After matching the franchise record with 14 first-half assists, Harden tied his career high with his 16th early in the third quarter. The Los Angeles native managed only six points in the fourth quarter, going 1 for 5, and his teammates were a combined 5 for 16.
Hall of Famer Bill Walton proudly wore a purple Lakers T-shirt to his son's official coaching debut. Walton's mother and three brothers also attended the game. "The Walton force will be strong tonight," Luke said with a grin. "There's definitely nerves and excitement right now, but mostly there's no time to think about how incredible this is, and the opportunity. It's more focused on watching film and getting the prep work in for tonight's game."
The Lakers fired D'Antoni after he went 27-55 in 2013-14, the first of a franchise-record three straight non-playoff seasons. When D'Antoni was asked before the game about reflecting on his time in LA, the coach quickly quipped: "I try not to. ... No, I loved it. I actually did. Manhattan Beach is probably the greatest place to stay. Great friends. They treated me nice, (Lakers owner) Jim (Buss) and (general manager) Mitch (Kupchak). It just didn't fit. It just didn't work."
Lakers: Metta World Peace began his 17th NBA season, picking up three fouls in his first two minutes while guarding Harden. ... Before the game, they solidified their young core by picking up their 2017-18 contract options on Russell, Randle and Larry Nance Jr. ... Jack Nicholson, Denzel Washington, director Peter Berg, YG, Kendall Jenner, Karlie Kloss, Dodgers president of baseball operations Andrew Friedman and NBA Commissioner Adam Silver attended the game.
Rockets: At Dallas on Friday in the opener of a home-and-home series.
Lakers: Open a four-game road trip at Utah on Friday.
