Swingman Chris Douglas-Roberts and forward/center Melvin Ely signed their nonguaranteed contracts with the Mavs.
Expect them to have a short stay in Dallas. They might be headed up the tollway to Frisco, where the D-League Texas Legends are located.
The Mavs' roster, which currently has 18 players, has to be trimmed to 15 by Monday. They're likely to keep center Eddy Curry as the 15th man, but that would require a resolution that officially removes suspended guard Delonte West from the team.
