From the recent Silverberg interview where he commented on Cronin, here's bit about Silf unable to turn the offensive switch on (for the World Championships) b/c he was trained to play defense:
Jakob smiles as he tells the story.– That was a real wake-up call for me. I had one year left with Anaheim and we had decided to go home. I thought: if I’m going home to Sweden, it will be with expectations, I have to make a real push and show some f***ing embrace to turn this around.”But how could it turn out like it did in the World Cup?– I know damn well, actually. I think I was a little mentally broken. We had missed the playoffs several years in a row. I had had a defensive role in Anaheim, where I just played simply: one touch, edge out – not offensive. I couldn’t switch to the WC. I wanted to contribute more offensively, but had a hard time getting into situations and the puck wasn’t bouncing my way.
Silf's +4 rating was one of four players with + rating who played double digit games for the Ducks last year. He only played for Cronin for one season and it affected his ability to tap into an offensive mindset for the WC.
Not saying he wasn't forced to play more defensive minded by Cronin, but I think he largely put himself in that position because the last couple-ish years before, his offense/hands really went downhill. Sure, he didn't have the best line mates, etc... but his defense was really the only thing he seemed to still have an impact on.
