WINNIPEG — Dallas netminder Jake Oettinger went from the outhouse to the penthouse. After surrendering six goals in a 7-4 loss to the Calgary Flames in his last outing, Oettinger rebounded by stopping all 27 shots he faced to record his first shutout of the season, leading the Stars to a 2-0 triumph over the Winnipeg Jets on Tuesday night. “That’s goaltending in a nutshell,” Oettinger said. “You feel like you’re at rock bottom, then get a shutout a couple of days later. So, I’m going to enjoy it
