All-Star center Dwight Howard sends tweet saying he is signing with Houston Rockets

Dwight Howard never grew comfortable playing with Kobe Bryant and for Mike D'Antoni.

Once a wide-smiling, fun-loving big guy, Howard lacked that joy in Los Angeles.

The Rockets are confident he'll find it again in Houston.

"We're going to get a smile back on his face that hasn't been on it for a couple of years because of various things, injury and maybe the team situation he was in at the time," general manager Daryl Morey told Comcast SportsNet Houston. "He's going to have a smile back on his face."

The Rockets were the ones beaming Friday, thanks to Howard's choice to take less money in hopes of more happiness.

"I've decided to become a member of the Houston Rockets. I feel (it's) the best place for me and I am excited about joining the Rockets and I'm looking forward to a great season," Howard wrote on Twitter.

He leaves behind an extra $30 million and an offense under D'Antoni that he was never fully pleased with, joining a Rockets team that could become an immediate contender in the Western Conference with the All-Star center in the middle.

USA Today first reported earlier Friday that Howard would join the Rockets, where he will team with All-Star James Harden to give the Rockets a potentially potent inside-outside combination.

That didn't quite end the Howard saga, which has dragged on a couple of years. Howard spoke again with the Lakers amid reports he was changing his mind.

Turns out, he was just saying goodbye.

"We have been informed of Dwight's decision to not return to the Lakers," Lakers general manager Mitch Kupchak said in a statement. "Naturally we're disappointed. However, we will now move forward in a different direction with the future of the franchise and, as always, will do our best to build the best team possible, one our great Lakers fans will be proud to support.

"To Dwight, we thank him for his time and consideration, and for his efforts with us last season. We wish him the best of luck on the remainder of his NBA career."

But it was the Rockets, who brought Hall of Fame center Hakeem Olajuwon with them when they made their pitch to Howard on Monday, who beat out the other teams.

And now Howard will follow the likes of Olajuwon and Yao Ming in Houston's middle.

The deal can't become official until July 10, after next season's salary cap has been set. The Rockets can give him a four-year deal worth about $88 million, a year less and far below the $118 million the Lakers could have offered.

The Lakers acquired Howard last August from Orlando as part of a four-way trade that also included Philadelphia and Denver.

He averaged 17.1 points and 12.4 rebounds in 76 games, good numbers but far from his usual dominant play in eight seasons with the Magic as he played his way back into shape following back surgery.

Bryant apparently won't miss him. Though he took part in the Lakers' meeting with Howard on Tuesday, the five-time champion posted a photo on Instagram of himself and Pau Gasol, the Lakers' remaining big man, shortly after Howard's decision.

Howard's awkward departure is right in line with the confusion that's followed him over the last few years.

The No. 1 pick in the 2004 draft was one of the NBA's most popular and likable players, an Olympic gold medalist who led the Magic to the 2009 NBA Finals — where they lost to Bryant and the Lakers.

But he decided a couple of years later that he wanted out of Orlando, and the Magic eventually gave his agent permission to negotiate with the Nets, Mavericks and Lakers about arranging a trade.

Yet Howard would later agree to not opt for free agency, remaining with the Magic for the 2011-12 season. Howard's season ended prematurely when he needed back surgery, and Orlando finally dealt him to Los Angeles.

The Rockets believe he'll find that chemistry in Houston.
