LOS ANGELES (AP) — Coach Doc Rivers has said he'll resign from the Los Angeles Clippers if Donald Sterling remains owner, the team's interim CEO testified, saying such a move would be a "disaster" for the franchise. Shelly Sterling is scheduled to return to the stand Wednesday as the final witness, with the two sides returning for closing arguments next week. Parsons, a former chief executive at Time Warner and Citigroup who took over leadership of the Clippers in May during the media blitz surrounding the banishment of Sterling, said under questioning by Ballmer's lawyer that the departure of Rivers would "accelerate the death spiral" of the Clippers. Parsons said he fears there would also be an exodus of key players, including team captain Chris Paul, who heads the NBA players union. Later Tuesday, Sterling fired off another legal volley, filing a new lawsuit against his wife, the NBA and league Commissioner Adam Silver that alleges fraud, breach of contract, unfair business practices and infliction of emotional distress.
