I don't think they should trade Giroux or Voracek. I wouldn't trade Couturier or Laughton either but anybody else from the current roster should be explored even guys like Simmonds and B. Schenn. Obviously the return would have to justify moving those two. As for the rest of the roster, I don't think you need to be blowed away with the return to justify moving them. Clearing salary, opening rosters spaces, and getting picks and or prospects should be the goal for the rest of the season. Doing those things would make this team a loser for the rest of the season which is what I mean by blowing it up.
I get what you're saying. At the same time, the rest of the league knows that the Flyers are in a predicament with regards to contracts and any team that will deal with them will want a sweetener in order to take on the contracts of a Lecavalier or an Umberger or a MacDonald (and I'd hate the idea of adding an Alt or an Aube Kubel or Friedman just to make a deal).
In terms of moving Coburn, Grossmann and others, the Flyers are best served to wait until the deadline. By that time, there'll be a clear idea as to who will be in line to qualify for the playoffs and who are considered serious Stanley Cup contenders. The Flyers can hold an auction so to speak and get the absolute best deal they can. If they deal now, they're losing out on value.
I'm sure Grossmann might return a low second or a high 3rd round pick at the deadline. Coburn should be able to land a young roster player and a blue chip prospect or a first. Another guy they should shop is Streit. I hate the idea of moving him, at the same time, Streit's just turned 37 and nobody knows if he can keep producing at the rate he's at. Might as well sell high and see if he can help a contender. It'll probably mean having to take a bad contract back that will expire, but moving Streit could also mean multiple prospects and a first round pick (maybe not 2015, but 2016).
The biggest thing currently hindering this club though is an adequate coach and staff. I've harped on it a bit in other posts, but the loss of John Paddock really set this club back. I'm starting to believe that Hextall let him walk so that he can see if Berube is capable of the job without the benefit of having an experienced assistant to help out with line matchups, defensive pairings, defensive game plan and play, etc.....Clearly Berube is in over his head and Hextall will be serving the franchise best by firing him at the end of the year.
