It's all Jacques Lemaire's fault. (his "trap" system allowed crappy teams to neutralize superior offenses)
http://en.wikipedia.org/wiki/Jacques_Lemaire
Lemaire is known for his unorthodox coaching style for several reasons: first, he prefers a defensive-minded system, often using a strategy called the neutral zone trap,[4]. Second, Lemaire rarely uses permanent lines preferring to use mixed line combinations during games. Lemaire is also regarded as one of the best teaching coaches - developing young players while working well with veterans. However
his emphasis on "defense first" has often been controversial, both inside and outside the dressing room. This perhaps, has led to some conflict with star players like Marian Gaborik (formerly with the Wild) and media criticism. An example was provided by Terry Frei of ESPN.com in an article posted on August 4, 2008:
He [Lemaire] helped drag down the entertainment quotient in this league, and despite all the talk about the Wild being a skating team that uses speed and pounces on turnovers, not all the elements of the trap have disappeared from Minnesota's game. You'd think the State of Hockey is going to tire of that at some point, especially if the Wild slide this season and it drives Marian Gaborik away next summer.[5]
