I don't really see Laughton and Laczynski as having anything to do with each other. Laughton is a LW or 4C; Laczynski is pretty strictly a RW. Maybe he can play center in a pinch, but he's a RW in terms of projections. Could he play LW? Versatility is a strength, but I'm not sure I've ever seen him there.
If and when NAK signs his cheap multi-year deal this offseason, the 4RW job should be his for the short-term future. He probably has more to do with blocking Tanner than Laughton. I think Laczynski is more purely skilled than NAK -- people will see how strong his below the dots game is, particularly as a poised playmaker -- if we are talking the 3RW job. But the Flyers have so many moving parts between Patrick and Frost and Farabee and even Oskar (though it would be foolish to make any assumptions for next season).
Pitlick is strictly a 4RW and NAK has made him expendable entering the UFA market. That's a no brainer for me talent-wise and contractually. We have Raffl under contract 1 more season and he can play anywhere, though should be pencilled in at 4LW. Laughton is also under contract 1 more season, and though I think it's a good time to strike while his trade value is at a high for several reasons (unsustainable numbers, roster reasons, disinterest in re-signing to market value), I'm not sold they will. Though perhaps that might be better than signing Grant to multiple years or something. It wouldn't even surprise me if it's Raffl they trade, though I would disagree.
Where does this leave Laczynski? I have no idea. Something would have to give. Perhaps he's first call-up, but I do believe (and Flahr seems to agree) he's NHL ready.
