http://sports.espn.go.com/nba/news/story?id=3464478 NEW YORK -- Disgraced NBA referee Tim Donaghy has exaggerated his cooperation in a gambling investigation in hopes of lessening his prison term and avoiding paying hefty restitution, prosecutors said in court papers filed Friday. He also has minimized his own role in the scheme, according to the filing in Brooklyn federal court. Prosecutors rebuffed defense arguments that Donaghy should get a break on his sentence for voluntarily coming forward and giving prosecutors inside dirt about alleged game-fixing and other misconduct by other referees and league officials. In the court papers, prosecutors said that by the time Donaghy decided to cooperate last year, "the government had a clear understanding of the criminal conspiracy, and who was involved." Though he deserves credit for giving investigators information on his two co-defendants, his claims of other internal NBA corruption "did not lead to evidence of prosecutable federal offenses," the papers added. Defense attorney John Lauro declined comment Friday. The 41-year-old Donaghy pleaded guilty last year to felony charges of taking cash payoffs from gamblers in the 2006-07 season. He faces up to 33 months in prison at sentencing, set for July 14. His attorney has argued that it's unfair that Donaghy's co-defendants, a professional gambler and a middleman who also pleaded guilty, are facing less time - up to 16 months and up to 18 months, respectively. Their sentencing is scheduled for July 11. espn.com 6/17/08
