The Dallas Mavericks announced today that they have selected forward Ahmad Nivins with the 56th overall selection of the 2009 NBA Draft and have acquired 45th pick Nick Calathes from the Minnesota Timberwolves in exchange for the future second round pick of the Portland Trailblazers that the Mavericks obtained in a trade on June 24, 2009.

Nivins (6-9, 242) finished his career as the third-leading scorer in the history of Saint Josheph’s University with 1,789 points. He was named the Atlantic 10 Player of the Year following his senior season after averaging 19.2 points and 11.8 rebounds while shooting .612 from the field and starting all 32 games. Nivins was All-America honorable mention and became just the second player in A-10 history to lead the league in field goal percentage for three consecutive seasons.
