As to the Wilson question. Let's suppose it was Trotz, all by himself, made that decision. It's either gonna' be because of the depth we've had over past years at C, or the defensive responsibility.
Last offseason, you're GMDP and the best O player you sign skates what position? Right, Cullen signed to be your #1C, even though we still have Fish/Leggy/Goose, who we've been skating at C for years. Rightly or wrongly, you know that Trotz is still gonna' skate them, not CWilson, at center.
Now, if you're Poile, don't you either have a conversation with Trotz and tell him you'd like Wilson skating in the middle for the longterm good of the team, or else not hand him a guy that you say is gonna' be your #1C?
That's an example of where I disagree with some of the "trotz skated guys outta' position" kinda' talk. While he's the coach and filling out the lines nightly the GM is acquiring the assets and has much more influence over the development in the minors, including what position they're skating.
I'm quite sure Stalberg's failure had something to do with Trotz going, and if the decision wasn't final before he got here, the way MDZ was handled and integrated did too. Clearly, over the years, Poile has acquired a few guys that didn't work out well in Trotz's eyes, and Poile hasn't been too happy (apology to Vishnovski, as an example). BUT - if you have a prize pick who you traded up to get, and it's been several years and the coach isn't using him in the way you find appropriate, why would you hand that coach more ways to get around using the guy the way you see he should? You sign a wing, don't ya', rather than a C, because it's your job to assemble the right talent.
