The Mavericks' decision-makers don't know how good their odds are of landing LeBron James or Carmelo Anthony in free agency.

They are certain, however, that those odds got a heck of a lot better in the last few hours.

"It makes us real players for LeBron [or] Carmelo," a team source told after completing the trade that brought center Tyson Chandler back to Dallas.

The Mavs will attempt to convince one of the perennial All-Star small forwards to join Dirk Nowitzki and Chandler in a frontcourt that they believe would be the best in the league.
