While Brisbee is best known for covering the Giants, he says that the Giants are not the team that has made Lincecum the offer. In his article Brisbee speculates as to who it may be. Possibly the Padres, for whom Lincecum could be seen as a reasonable upgrade. Or, possibly, a non-west coast team with which the west coast-residing Lincecum would prefer not to sign, but whose representatives could be leaking in order to inspire a west coast team to match with a guaranteed offer of their own. His speculations seem pretty reasonable.
