I'll bet on Trotz going to Winnipeg (talent, but needs defensive structure, and it's homecoming) or Vegas (very talented veteran team that needs a strong hand to get over the top, shades of the Caps). There is no reason for him to come here, he's made enough money that an extra million a year (and Nevada has no income tax) will move the needle.
People whining that Fletcher is taking his time don't have anyone to point to other than Julien, Maurice, Torts, etc. And who wants them? Gronberg is the only out of the box candidate who is available.
The top candidates won't become available until either they're fired for not going deep into the playoffs (Sullivan, Cassiday, Keefe) or are assistants to teams in the playoffs. So why would you rush when you can wait and see who becomes available. If you have an AHL HC on the list, they're not going anywhere quickly.
