re: Laughton
I don't think anyone wants to simply replace Debrincat with Laughton and I definitely don't. But I want to talk about Laughton the player and why I think he would be a very good addition to this team.
Role
First off, Laughton is probably not a true top 6 player, much in the same way that Connor Brown, JG Pageau, and Nick Paul are/were probably not true top 6ers.
Like those guys, he is probably best on your 3rd line but he can also fill in adeptly at LW OR at C in the top 6. Laughton is a "glue" player; he works on every line and he consistently does the right things. He very rarely has down stretches, even if he goes periods without scoring. He was the only Flyer to wear a letter last season.
Skillset
Like those other guys, Laughton is an above average play driver. Not elite or even very good, but consistently above average. Also like those other guys, he has shown the ability to continue to drive play as his minutes and responsibility have gone up.
Laughton is not huge or super intimidating but he is quite physical, willing to fight (non-fighters), and solid. He skates well and protects the puck well, and can make basic power moves to the net. He is highly-engaged, gritty, and tenacious. He can handle himself after whistles and plays hard between them.
Laughton is far from a natural goal scorer, with a career high of 18 and never pacing for much better than that. Compared to the above players, Brown is probably a pretty decent goal-scoring comparison. Moreso than Brown, though, Laughton has the ability to score from mid-range (beyond the dot). He has a good, hard, accurate shot, and has actually out-shot (sh%) his line-mates in all but 1 season (16-17). Laughton has shown a tendency to shoot more when he plays up in the lineup, which may be because he is competent on the rush. He sends and receives passes pretty well and shows poise and skill on the rush & on breakaways.
Special Teams
Laughton was used on the PP for the first time in his career this year, but he was on Philadelphia's league worst PP. Still, he picked up 5 goals & 9 points in 136 minutes, and his PP Pts/60 were just a bit below average (and better than guys like Hall, Duchene, Kreider, Aho, Compher etc). By no means is he a legitimate PP1 option, but he has shown decent promise as a PP2 option and perhaps even a fill-in on PP1 in case of injury.
Laughton has been a very good PKer for a while now but he added an offensive element to his PKing repertoire under Tortorella's new system. He is fine on face-offs.
Contract & Career Outlook
With three years remaining at 3mil and a contract that takes him just beyond his 32nd birthday, Laughton is locked up for cheap during what will likely be his prime years. Laughton took time to come into his own, but has slowly developed into a player who can impact the game at all levels, and now seems confident doing so in any situation. He is not a game-breaker, but he is consistently good, night in & night out and in whatever role he's placed.
TL;DR: Laughton does it all, and he does it all well. He is not a standout at any area of the game but he is a standout pro: he is consistent, reliable, and competent (at least) at every facet of the game.
Want Konecny & Laughton if we are dealing with the Flyers.
Obviously my thoughts on Laughton are clear... and while Laughton is not enough for Debrincat, Konecny carries a whole lot of value. That trade would be a coup imo, even if we end up just trading Konecny after 1 season.
