I'm pretty sure that Marleau would have accepted league minimum if he could play for the Sharks. In fact there's actually a small risk that no team wants him for league minimum. I think he's worth that and more, but GM's tend to look several years ahead, so Marleau is really only interesting for contenders or maybe as a mentor. Marleau is not a high profile scorer anymore, but he could certainly help pitch in for a cheap price. The Sharks needs a RW first and foremost, so he's not really a good fit. I don't think their young players are ready to step up yet, so signing Marleau for a year would have been fine, and made them more competitive, but maybe Doug figured that he didn't want to give him 2 years, or couldn't see himself signing for 1 year and then extending him further, so he figured that it would be better for Marleau to go somewhere else and end his career with a single team that would be more open to giving him several years. Of course, he needs 2 more years to break Gordie Howe's record.
