Right, and you think the Penguins hired him so he could abandon everything that's made him successful and become an "offense killer?" What evidence do you have to support this? And if you point to last season, I'd point out that the Penguins effectively had no transition game as most of their NHL-calibre dmen were on the shelf.
I just don't understand what would prompt one to say that MJ is an "offense killer" when there's not a shroud of evidence over the course of his entire career that suggests that's true.
