The Mavericks drafted Deividas Sirvydis at No. 37 overall in the second round and sent his rights to Detroit for the rights to Roby and two future second-round picks. Dallas didn't have a first-round pick in the June draft.
The 6-foot-8 Roby skipped his senior season at Nebraska to enter the draft. Roby averaged 11.8 points and 6.9 rebounds in his final season with the Cornhuskers.
Roby averaged 8.8 points and a team-high 5.2 rebounds in five games with the Dallas summer league team in Las Vegas.
