Jeff Caplan reports that while the Dallas Mavericks would like to sign summer league participant Jeremy Lin to a contract, they are not alone.

As a true point guard, the 6-foot-3 Lin was more dazzling, and at times more productive, than Rodrigue Beaubois on the Mavericks' summer league squad. He opened more eyes with each performance. He is in contract discussions with the Mavs, Los Angeles Lakers and an Eastern Conference team.

But his agent, Roger Montgomery, said Monday that new teams are now involved and that Lin is sorting through it.

Dallas only has Jason Kidd and J.J. Barea for true point guards on its roster and may have to depend on the raw Beaubois for some minutes at the position.
