The Mavs waived Ely and Douglas-Roberts on Sunday morning, before they even practiced with the team.
It's a good bet that they'll end up on the roster of the Texas Legends, the Mavs' D-League affiliate. The Legends now own the rights of both players.
That trims their roster to 16 players, one more than the limit by Monday's deadline. The Mavs are likely to part ways with West permanently by then, making room for center Eddy Curry to stick around after his solid audition in Friday's preseason finale.
