Miller, 41, who was living with his girlfriend in Edgewater, pleaded guilty last fall to first-degree assault and carrying a handgun.
The allegations stemmed from a family argument at a cookout April 17 at a friend's home. Exactly what took place there, and what led Miller and his girlfriend to go to the house of her brother, Jason Worley, and hit him with a handgun, remained unclear.
Deputy State's Attorney Thomas J. Fleckenstein said Miller was seen beating Worley in the street outside the home. Worley needed 11 staples in his head to close the wound.
Hackner sentenced Miller to five years in prison, suspending all but the one year, and recommended work release. After his release, Miller will be on probation for five years. Miller's girlfriend said she would help him look for a job.
Paul Mack, Miller's lawyer, said his client hopes to return to Arizona, where he has family, and would ask Hackner to amend the outcome to probation before judgment.
Miller, then listed at 6 foot 9 and 280 pounds, played for six NBA franchises, mostly in the 1990s, including the Phoenix Suns, Detroit Pistons and Toronto Raptors.
