Amr Alfiky/AP file photo General manager Stan Bowman’s quadruple espresso somehow wore off just in time. After a frenzied offseason of transforming the Blackhawks’ roster, he appeared just as calm and stoic as usual Monday, discussing the many trades and signings as the action begins to subside. “What we’re hoping for is a competitive team that’s pushing for the playoffs,” Bowman said. “That’s why we all do this. Certainly, some years it’s more likely than others . . . [and] this year, we’re looking to take a step forward. There’s a lot of reason for excitement and optimism.”
