The AP reports: Disgraced basketball referee Tim Donaghy told investigators in the NBA betting probe that relationships among officials, coaches and players “affected the outcome of games,” his attorney said. The league said the charges were unfounded. Donaghy’s attorney made the assertions in a letter filed in U.S. District Court in Brooklyn on Monday, in which he argued that his client should be sentenced to probation because he fully cooperated with prosecutors and has been undergoing treatment for his gambling addiction. The attorney also suggested that Donaghy told investigators about the gambling activities of other NBA officials and about a referee that passed “confidential” information to an unidentified coach.
