Dwight Howard says he is happy again.

The star center has put his lone disappointing and drama-filled season in Los Angeles behind him. He says he is ecstatic about joining the Houston Rockets and helping the young team compete for a championship.

Howard says: "I'm in a better place mentally, physically and spiritually now."

His delight is evident in watching him interact with his new teammates. He wears a broad smile fits of laughter are common as he chats with his fellow Rockets.

Howard spurned the Lakers to sign an $88 million deal with Houston, joining James Harden and a team that made the playoffs last season for the first time since 2009.
