Elliotte Friedman reported on Hockey Night in Canada that a mystery team (mystery to us, anyway) approached the Sharks about acquiring Patrick Marleau. Mr. Shark has not been asked to waive his no movement clause, so it's safe to say San Jose hasn't quite heard what they wanted to yet.

Even if the Sharks get offered a package they like, I'd be very surprised to see Marleau accept a trade to just about anywhere. He's lived in San Jose for a very long time. It's his home and, more importantly, it's where Joe Thornton lives. Still, this is probably something to keep an eye on, if for no other reason than to find out who thinks they can pry Marleau from San Jose's grip.
