Through two games, Blackhawks rookie Teuvo Teravainen has yet to record a single shot on goal. He didn’t have any Friday night, either, because he was a healthy scratch. The two aren’t necessarily directly related, but coach Joel Quenne­ville would like to see Teravainen be more aggressive. The 19-year-old Finn is a playmaker first and a goal-scorer second, but at least twice Thursday night against the Boston Bruins, he gave up a point-blank shot in favor of a low-percentage pass through traffic. Quenneville wants to see him defer less, and shoot more. “Offensively, you think of shooting,” Quenneville said. “He has the puck in some good areas there, and he looks like he wants to dish a lot of times, but think of getting it to the net yourself, and get some action off of that.” That said, Quenneville said he liked what he’s seen from Teravainen so far. If scratching him was to rest him and continue easing him into NHL life, or was a calculated move to keep his games played to less than 10 and preserve his three-year entry-level contract, Quenneville wasn’t letting on.
