MERCURYNEWS.COM: In the wake of the San Jose Sharks re-signing Joe Pavelski to a multi-year extension, GM Doug Wilson acknowledged he’s had talks with ageing Sharks stars Joe Thornton, Patrick Marleau and Dan Boyle, who are due to become unrestricted free agents next summer.

SPECTOR’S NOTE: The Capitals management can afford this stance. No offer sheets are coming for Johansson during a summer in which the salary cap has declined, plus he’s coming out of his entry-level contract and has no arbitration rights, which gives him almost no leverage. The Capitals are likely pushing for a “bridge” contract (two-three years long) and probably around $2 million per season.
