Nearly a week after the Indiana Pacers offered talented but controversial guard Lance Stephenson a five-year, $44 million contract, the two sides remain far apart on a deal, according to sources close to the situation.

Although his desire is to remain with the Pacers, a disappointed Stephenson began exploring the free-agent market after receiving what he felt was a low-ball offer on Tuesday, sources said.

Stephenson has drawn interest from the Dallas Mavericks and Los Angeles Lakers, although both teams have other free agents prioritized above Stephenson, according to sources.

Dallas, believing it likely will lose out on both LeBron James and Carmelo Anthony, will attempt to sign Chandler Parsons away from the Houston Rockets. The Mavericks also have Luol Deng and Trevor Ariza in their sights, sources said.

But Stephenson has also recently emerged as a target of the Mavericks. A month ago, or even a few weeks ago, Stephenson was not on Dallas' radar, but over the past few days the Mavericks have registered their interest, according to sources.

Dallas is intrigued by Stephenson's versatility. He led the NBA in triple-doubles with five last season, and his 7.2 rebounds per game, highest among the league's guards, could help a Mavericks team that was among the league's worst in rebounding.

Like the Mavericks, the Lakers are targeting the summer's superstars -- James and Anthony -- ahead of Stephenson. They also have an interest in Deng and Ariza, but Stephenson remains a possibility should their other plans fail to materialize.
