All signs point toward some important signings for the Blackhawks in the coming months. General manager Stan Bowman said he expects to ink Anthony Duclair, Ryan Hartman and Vinnie Hinostroza, all restricted free agents at season’s end. “We have a lot of guys in that category,” Bowman said. “John Hayden as well. … I’m confident we’re going to get those contracts all worked out.” Duclair, Hinostroza and Hayden will be eligible for arbitration, as will Tomas Jurco and Erik Gustafsson, according to Bowman also said he’s confident the team will sign Dylan Sikura, a 2014 sixth-round draft pick who is playing his final season for Northeastern University. “I don’t have any reason not to be,” Bowman said.
