Sources: Mavs on verge of trading Calathes to Memphis

The Dallas Mavericks are in advanced discussions on a trade that would send former second-round pick Nick Calathes to the Memphis Grizzlies for future draft considerations, according to sources with knowledge of the deal.

The Mavericks acknowledged in recent weeks that they were likely to deal Calathes -- their 2009 second-round pick who spent the past four seasons playing overseas -- if a deal was struck to sign Israeli point guard Gal Mekel.

Sources told ESPN.com that Dallas has since been in discussions with multiple teams on a Calathes trade, but is now on the verge of sending the pass-first point guard to the Grizzlies after Calathes established himself as one of the best floor generals in Europe last season.

The 6-foot-6 point guard, now 24, visited Dallas in June to meet with team officials and audition for Mavs coach Rick Carlisle. But Dallas opted to offer a three-year guaranteed deal at the league minimum to Mekel, who then turned in a strong summer league performance running the team under Mavs assistant Monte Mathis.

Calathes was determined to jump to the NBA this season after averaging 12.9 points, 6.7 assists and 5.9 rebounds and earning MVP honors in the EuroCup for leading Russia's Lokomotiv Kuban to the second-most prestigious team title in European club ball. Houston Rockets guard Patrick Beverley, who rose to prominence during last season's playoffs, was EuroCup MVP in 2012.

Calathes is under contract to Lokomotiv Kazan in 2013-14 but has an NBA out in the deal that allows him to finally jump to the best league in the world after playing collegiately at Florida.
