Im not sure what kind of "goonish" tactics you are talking about. How about an example?
You dont think that downey running Laperierre twice in the same game is "goonish"? That is more "goonish" than anything the Avs have done this year.
I guess it is obvious that the Avs are goonish, being that when the wild tried to goon it up, the Avs went crazy and gave them cheap shots all over the ice!, Right?
