Partially will depend on coaches plan for deployment.
I can say this, since I published this before I "went dark", I would do with the Jets forwards something like what Maurice did with the dmen for 2015-16.
Jets have some interesting pieces, but who seem to be fairly incomplete players (maybe in part due to youth). Lowry is just one example; he scores like a 4C at evens, but the rest of his game is much, much better than a 4C.
The Jets also have some good, young players that I think deserve a shot with quality linemates.
I would run 3 scoring lines and one defensive line for the bulk of the game. With each line being anchored by the Jets' 3 best results drivers: Scheifele, Wheeler, and Perreault. Other linemates will vary a bit game to game depending on health, chemistry, etc.
x-Scheifele-x
x-x-Wheeler
Perreault-x-x
The x's will be 6 of Little, Laine, Ehlers, Connor, Roslovic, and Petan, maybe Dano is a choice, if he garners the conditioning to keep up with these lines, and maybe Armia is a choice, if he takes a development jump.
Copp and Lowry can fill in a pinch, but honestly I view those two, and Armia and Matthias, and maybe Dano, as more suited for the defensive line.
Now how you set up the 3 scoring lines will depend on how you want to divvy up TOI. If you want top heavy, Little will go on the Wheeler line, and you probably put Ehlers and Laine with Scheifele. Personally I'd like 3 lines of similar ice time, so you put Little with the Perreault line.
Now what makes this different than usual, and similar to the Maurice dman deployment 2 seasons ago, is the lines adjust when the Jets are leading.
The above lines would make the Lowry line a heavily used 4th line, sort of like Kruger in Chicago. But, I would lean on him a lot more when leading.
What I'd do is when leading you reset to a top6/bottom6 system. You sit the 3 weakest players in the top 9, and basically make them a sheltered 4th line, form a new top 6, and the Lowry line takes more mins while reducing chances against.
So, just one of many possible examples of this would be...
First two periods, or trailing in 3rd:
Ehlers-Scheifele-Laine
Petan-Roslovic/Little-Wheeler
Perreault-Little/Roslovic-Connor
Copp/Dano-Lowry-Armia
Matthias
Leading in 3rd:
Ehlers-Scheifele-Laine
Perreault-Little-Wheeler
Dano/Copp-Lowry-Armia
Petan-Roslovic-Connor
Matthias
Maurice did this in 2015-16 where he sat Stuart and Chiarot in the third, pushing Trouba with Byfuglien, whenever they were trailing.
I like this set up because:
* uses players to their strengths
* gives Lowry line more ice time than a 4th line
* shelters young offensive players with quality linemates
