(undated)  --  The race to sign free agent big man LaMarcus Aldridge is on.  The Lakers are reportedly out of the running after Aldridge was not impressed during a meeting between the two parties.  The Blazers along with the San Antonio Spurs, Houston Rockets, Phoenix Suns and Dallas Mavericks all reportedly remain in contention.  Aldridge averaged 23.4 points and 10.2 rebounds in his ninth year in Portland last season.
