Dodgers GM Ned Colletti said Thursday that while signing Matt Kemp to an extension will be one of his top priorities this winter, he will not put a time limit of Opening Day on the negotiations, as Kemp's agent Dave Stewart has suggested. "Whenever you have a negotiation, one side's always got the right to say they're not doing anything," Colletti told ESPNLosAngeles.com on Thursday. "Or two sides have the right to say that, or two sides have the ability to say, 'Yeah, let's do something.' So however that goes, we'll do what we can do from our side of it. We can't control the other side no matter who it is."
