The Flyers are in a tough predicament in regards to their defense prospects. The prospects need to be sheltered as they get adjusted to the NHL. The problem is the Flyers don't have very good veteran defenders or anybody who take 1st pair responsibilities. Coburn is the Flyers best defender but he has shown that he needs a steady veteran presence to play with as opposed to actually being one for a young defender. MacDonald has been a disaster. L. Schenn and Grossmann will be off the team after next season at the latest, not that they are any good, so that leaves only Streit as a good veteran presence. So the Flyers will need to acquire veteran defenders to not only mentor the prospects but also to take hard minutes until they are ready. But how do they do that without capspace?
Couturier is a great defensive center but IMO he won't ever be a dominant offensive player due to his speed. A bulk of goals scored at 5 on 5 in today's NHL is off of the rush. That is why teams that carry the puck into the zone score more than those that dump and chase. Couturier is great at carrying the puck into the offensive zone but not great at creating the great scoring chances on breakaways or 2 on 1 rushes because of his skating. A guy like Laughton could create those chances. So the question is what is Laughton going forward: a productive 2nd line center or a 3rd line center. If Laughton and Couturier both project as 3rd line centers then moving Couturier would be that bad of an idea.
Couturier for Myers could work out if the Flyers attached MacDonald to the deal but only in the offseason and coupled with other moves. If the Flyers could clear some cap space during this season by trading Coburn and Read or whoever, they can sign a guy like Methot (would prefer Staal but that is a pipe dream)to pair with Myers. Myers and Methot could take 1st pair minutes and shelter the kids until they are ready. Then at some point at the end of next year or the following season, Myers could be paired with Morin and Methot with Ghost, much like his was with Karlsson. The Flyers would have a hole at 2nd line center but they will probably take either a center or defenseman in the draft this year based on Hextall's comments about valuing those positions over wings or since they will be bad next year too, they could get the center then.
