Elton Brand has four more years to prove to Philadelphia he was no $80 million bust.

Year 1 was a disaster.

Brand's comeback from a separated right shoulder is over and the two-time All-Star power forward will have season-ending surgery on Monday. All the Sixers got in the first year of a five-year, $80 million contract from the player they expected to help win them a round or two in the Eastern Conference playoffs was 13.8 points and 8.8 rebounds in only 29 games.

"It's the most disappointed I've ever been in my career," Brand said yesterday. "This was supposed to be special. This was supposed to be winning, supposed to be fun. Management believed in me. I'm still not going to let them down."

The Sixers first said Wednesday an MRI revealed no new damage to his right shoulder, and he could play against Indiana last night.

The MRI results were reviewed by team doctor Jack McPhilemy and Dr. Craig Morgan, of the Morgan-Kalman Clinic in Wilmington, Del., who concluded that the initial tear of the labrum in Brand's right shoulder is responsible for a considerable decrease in the range of motion and instability.
