The problem is that the defense is no better than it was last year and with questionable health in Sekera it's concerning. The Ducks toyed with our defense for long stretches and their back end is far superior to ours.
Our defense was in the upper half of the league last season with Klefbom coming off a major injury, Benning being a rookie, and Nurse being young/hurt half the year.
Development from Benning and Nurse, more chemistry and development from Larsson and Klefbom (they're still young as well), as well as still having cap space and assets to improve the defence make your very tired and incredibly pessimistic post pointless.
