From Comcast SportsNetLOS ANGELES (AP) -- Dwight Howard missed a two-handed dunk on his first shot, and the night never got much better for the Los Angeles Lakers.When Howard and Steve Nash took their places alongside Kobe Bryant and Pau Gasol under the Hollywood spotlight, the Lakers opened a season of enormous expectations with an equally big dud of a performance.Darren Collison scored 17 points, Brandan Wright added 14, and the Dallas Mavericks spoiled the Lakers debuts of Howard and Steve Nash with a 99-91 victory over Los Angeles on Tuesday night.In his first regular-season game in a gold jersey, Howard had 19 points and 10 rebounds while missing 11 of his 14 free throws before fouling out with 2:02 to play.That's hardly the debut he anticipated after arriving in a trade with Orlando last August, but not much has gone according to plan in the first month for the Lakers' starters, who barely played together in their winless preseason due to injuries."It's not an excuse, but it will all come with time," Howard said. "We haven't had an opportunity to really play together as much as we want, but we're going to get it. ... We're going to chip away, and we're going to get better."The Lakers' superstar newcomers both had debuts to forget. Nash managed just seven points and four assists while trying to balance the Lakers' new motion offense with his own strengths on the pick-and-roll -- all while getting roundly outplayed by Mavs newcomer Collison."It's growing pains, and it's a struggle," Nash said. "We're out of sync, and we're going to probably have some more moments in games like that."O.J. Mayo had 12 points as the Mavericks pulled off a stunner in their opener, comfortably beating the Lakers without any help from injured Dirk Nowitzki. Dallas and Los Angeles both made big moves in the offseason, yet the Mavericks appeared to be much more together than their high-profile rivals."It's a great win," Dallas coach Rick Carlisle said. "If you execute in this league and have talent, you have a chance to win, and we did that. The Lakers are going to be fine. They've got a lot of new guys and a new system, but we were opportunistic tonight and got the job done."Bryant scored 22 points while playing on an injured right foot for the Lakers, whose loaded lineup followed up its 0-8 preseason with a largely passionless second-half effort in front of a sellout crowd expecting to see a super team capable of contending for the franchise's 17th championship -- a fact acknowledged by Bryant when he addressed the fans before the game."As you know, we have a lot of expectations this season," Bryant said. "We're trying to live up to the expectations. We're trying to bring another championship back to where it belongs, back to Los Angeles."Instead, the Lakers showed how much work they will have to do to challenge Miami and the NBA's best.Dallas steadily pulled away to a 16-point lead in the second half, never allowing any serious runs by their disjointed, disorganized opponents as the Lakers lost their opener for just the fourth time in the last 21 years."It's not the way we wanted it to go," said Gasol, who led the Lakers with 23 points and 13 rebounds. "We know it's not going to happen for us right away, but we've just got to stick with it."Vince Carter, Shawn Marion and Rodrigue Beaubois scored 11 points apiece for the Mavericks, who snapped a six-game skid against the Lakers over the past two seasons.Dallas also contained Howard by using his career-long free-throw ineptitude against him -- hardly a novel strategy, but one that worked particularly well when combined with Howard's opening-night nerves."When he had me in a bad position, I wanted to foul him," said Elton Brand, who had eight points and 11 rebounds in his Dallas debut. "Underneath the basket, he's a beast and he's hard to stop. I know he can dunk, and I know he can make those tough layups, so I'm playing the percentages. He obviously hasn't been a good free throw shooter, and tonight he was 3 for 14."The Lakers were 12 for 31 altogether from the free-throw line, a major factor in their inability to close the gap on Dallas in the second half."I've just got to stop thinking so much and get up there and make them," Howard said.Jae Crowder scored eight points in his NBA debut for the Mavericks, who are likely to be without Nowitzki for at least six more weeks while the German superstar recovers from arthroscopic knee surgery. Dallas also played without new center Chris Kaman, yet had little trouble containing the Lakers down low.NOTES:Dallas opened its season on the road for the first time since 2007. The Mavericks had opened the season against the Lakers three previous times, losing all three games. ... Howard was called for a flagrant foul in the third quarter for hammering Brand on an open shot in the lane. ... Katy Perry, Russell Brand, Floyd Mayweather Jr., Adam Levine, Jon Cryer and Los Angeles Galaxy stars David Beckham and Robbie Keane attended the game.

VANCOUVER – Playing for the first time since their bye week, the Sharks scored two goals in each of the final two periods to down the Canucks at Rogers Arena on Saturday, 4-1.
San Jose improved to 11-2-5 in its last 18 games, and increased its lead in the Pacific Division to five points over Anaheim and Edmonton.
After a lackluster first period without much action, the Sharks opened the scoring in the second.
Joel Ward took advantage of some confusion at the Vancouver bench, plowing ahead untouched for a breakaway. His attempt squirted just wide, but Chris Tierney pushed the loose puck to the front of the net where Tomas Hertl pounded it home at 3:31.
Vancouver tied it later. Brent Burns’ defensive zone turnover resulted in Daniel Sedin buzzing in a wrist shot short side on Martin Jones at 12:02.
The Canucks had a chance to take the lead on the power play later, after Micheal Haley jumped Joseph Labate for hammering Melker Karlsson along the wall. Bo Horvat was staring at an empty net, but fired the puck high with four minutes to go in the middle frame.
That allowed the Sharks to reclaim the lead on Patrick Marleau’s 22nd goal. The forward was set up beautifully by David Schlemko, who passed the puck through the seam, confusing Ryan Miller and allowing Marleau to tuck it in at 19:04.
Jones, who was outstanding for the duration of the game, made a key stop on Alex Edler’s wrist shot from the top of the circle with 20 seconds to go, keeping it a 2-1 San Jose advantage after two.
Mikkel Boedker added to the Sharks’ lead at 11:31, whooshing a wrist shot past Miller on two-on-one with Logan Couture. The goal, Boedker’s first in 20 games, was unassisted after defenseman Ben Hutton gave the puck away to the San Jose winger.
Couture capped the scoring with a power play goal, picking the top corner from the faceoff dot at 14:20.
Karlsson returned to start the third period. Early in the third, Labate answered the bell and fought Brenden Dillon, with Dillon seemingly landing more punches.
Vancouver was without five players due to a mumps outbreak in their dressing room, while defenseman Luca Sbisa did not finish the game due to the stomach flu.
The Sharks won their 10th straight game in Vancouver, including both this season, increasing what was already the longest winning streak ever by a Canucks home opponent. The road team has won 15 in a row, extending an NHL record.
The Sharks capitalized on their only advantage of the evening, scoring just their second power play goal in the last five games (2-for-13).
Vancouver finished 0-for-2 on the power play, with both of its advantages in the second period. The Sharks are 10-for-10 on the PK over the last six games.
Jones, a North Vancouver native, improved to 4-0 in his career at Rogers Arena with 35 saves. He’s 29-15-6 on the season, starting 51 of the Sharks’ 61 games.
Miller fell to 16-18-3 on the season, allowing four goals on 26 shots. He’s 10-6-0 in his long career against San Jose.
The Sharks were carrying just 12 healthy forwards, as Joonas Donskoi did not make the trip after coming down with the flu. Donskoi, who has been out since Jan. 24 after suffering an upper body injury, is close to a return.
Barclay Goodrow played in his second game of the season, skating on the fourth line.
Vancouver defenseman Evan McEnany was making his NHL debut, while Labate was playing in just his fourth career game.
The Sharks return home to host the Maple Leafs on Tuesday, and see the Canucks again on Thursday at SAP Center.
Saturday’s game in Vancouver kicked off a stretch of 22 games over 43 days before the playoffs.
