Mark Cuban expects to keep G Mike James after his second 10-day contract expires. Two 10-day deals is the max a player can sign under this CBA, so the Mavs either have to sign James for the rest of this season or let him walk. "So far, so good. No reason to think otherwise at this point," Cuban said. James has averaged 3.3 points, 1.1 assists and 1.0 rebounds in eight games as Darren Collison's backup. His contract expires Sunday at midnight.
