A big reason, of course, is the fact that Jake Oettinger missed a month of hockey due to a groin injury. The 25-year-old established himself as one of the best goalies in the NHL last season, so his absence was felt. But even before Oettinger was hurt, his numbers were down. He has a 2.96 GAA this season after posting a 2.33 last year. He is at .902 on save percentage after stopping pucks at a .919 clip last year. Now, some of that is because of the team in front of him. In trying to become a better scoring team, the Stars have slipped in their defensive coverage. In trying to create offensive potential throughout the lineup, the lads in Victory Green have taken a few more chances.
