The Giants have not made an offer to Manny Ramirez, but that is largely meaningless. Sources tell the Chronicle that the team has talked dollars and years with Scott Boras, trying to find a creative way to make this work. That the Giants have not sent a written offer to Boras is not a critical point. There are differences of opinion even within the walls at 24 Willie Mays Plaza over how aggressively to pursue Ramirez.
