The San Jose Sharks made steps to implement a culture change in the dressing room last off-season, and are expected to continue that process this year. Kevin Kurz of CSN Bay Area, speculates the Sharks could do something big before or at the draft later this week. “There’s a real possibility that there could be a blockbuster in the works involving one of the team’s core players. Would aging veterans Joe Thornton and/or Patrick Marleau prefer to relocate to a team that has a better chance of winning in the immediate future? Was Brent Burns shifted back to defense last season in order to increase his trade value? Is Logan Couture still happy here, after he was critical of the team’s “not great” culture? Is Justin Braun expendable after he struggled in the first year after signing a big contract extension? These are all fair questions.” The Sharks also have ample cap space and Kurz reports the possibility they get in the restricted free agent market. - See more at: http://www.tsn.ca/sharks-working-on-a-blockbuster-1.314689
