As you can see by the opposing views so far this is definitely a legit offer. I personally take the deal but ONLY if I know I can get Schwartz or Galychenyuk with that 8th overall. I believe that Schenn and Couture has similar upside in terms of their career but I prefer Couture right now as he's clearly the top dog going forward in SJ and the face of the franchise and while I feel Schenn will eventually be that guy in PHI (aside from Giroux of course) he's not there yet and will likely see limited PP and even top 6 minutes...so your production over the next year or two will hurt.
However I take the deal because looking at your team I don't think it's ready for a "title push" so stacking your cupboard full of good young up-and-comers is the way to go IMO. I love Schwartz/Galy as future studs (hell they may even better than Couture/Schenn over their careers)...so for that reason I like this deal for your team. While the other prospects mentioned are nice it's not enough to give up the sure production of Couture.
The other thing I'd add is before committing to this deal maybe just say that you're interested but not sure yet and feel him out on you giving up M. Richards over Couture. I like Couture more than Richards and feel he's a better fit on your team than Richards is...if the other guy like Richards as a wash to Couture (many would consider this) than it could work out for both sides...at the very least it's something to consider.
