From a Sens blog:
[T]he Red Wings are probably underachieving in the standings. They sit second overall in 5 on 5 Corsi and sixth in Fenwick. The power play has had success with 24.1%, good enough for fourth overall. The penalty kill is stronger, running at second overall and 87.9%. This should be a team in the hunt for the league lead, not sitting third in the division.
The Red Wings recently did not win for six consecutive games. During that span, they allowed nine goals and and still procured four points. If that's the worst "slump" of the season, Detroit is going to earn an invitation to the tournament at the end of the season with ease.
The slump sucked, but this is still a very good team. And guess what: aside from Gustavsson, everyone's healthy.
