The Blue Jackets scored enough last night to breathe with ease. Goaltender Sergei Bobrovsky, who had lived on a very thin line of near-perfection for three weeks, finally had a license to appear human. But when the Blue Jackets and Bobrovsky began to exhale early against a struggling but proud Nashville team, a 4-1 lead turned into a 4-3 eyebrow-raiser with only 74 seconds remaining in the game. The Blue Jackets held on for a 4-3 victory in front of 13,364 at Nationwide Arena, pushing their franchise-record point streak to 11 games (7-0-4). “There’s a lesson in there for us,” said Blue Jackets winger Vinny Prospal, who had three assists. “We got a win, and a win in regulation, which is the goal every night. And we got some bounces tonight and scored some goals, which is good for the guys in here. “But we have to learn from this. We have to know how to handle a game like this at the end. It should be a 4-1 win.” Nikita Nikitin, Mark Letestu, Derick Brassard and Fedor Tyutin scored for the Blue Jackets, whose four-goal output was their most since Feb. 26. Jack Johnson added two assists, and rookie Dalton Prout had an assist for his first NHL point. Bobrovsky, an NHL award-winner for two straight weeks, made 32 saves. That was the good news for Columbus, all tucked into the first 58 minutes of the game.
