Another thing about Green is, I'm not sure how bad he really is defensively. I mean, I'm positive he's not going to be some stud shutdown defender. But I always take reports about Washington players being "lazy" or "bad defensively" or "not a team player" with a grain of salt. They've bred a culture of lazy, defensively irresponsible, play for years. When guys go there, they play poor defense and are lackluster, and when they leave they play good hockey.
I think part of the reason why they picked Trotz was to change all that. Green has the skating and size to be a decent defender, not great...but decent. Like Rafalski. Could Green be that for someone other than Washington? I don't know. But I'm pretty positive he's never, in his entire career, been asked to be up to this point.
