I think you may be underestimating Minny somewhat. Their top six is now includes Parise, Heatley, Koivu, and Setoguchi. Granlund could very well make the team this year and Bouchard is a good player when healthy.
Parise and Suter are the "lipstick on the pig" in Minny. The Wild are better but they will still struggle mightily to make the playoffs. These signings do not make Minny a powerhouse.
Their defense is a little thin after Suter and Gilbert but they did draft Dumba. They have a good goaltending tandem.
It's too early to call them a powerhouse but they have the makings of a pretty darn good team.
