Here are my thoughts on the matter:
A more balanced lineup composition will mitigate some of the defensive challenges. Instead putting all your offensive players together and all of your defensive players together (Moe likes to specialize his lines) spreading those elements around will help make up for certain deficiencies. We have enough solid defensive players that we can spread them around a bit.
- The top line was not a defensive liability with Ehlers on it. Right now you have Scheifele trying to carry all the mail in that regard. If he has help from one of his wingers (Sorry but Wheeler is very mediocre in his own end) then the line will be fine.
- Roslovic contrary to what most people think is a pretty balanced player, good on offense and defense which is why his line with Perrault and Appelton have had good success.
- That leaves two lines to solve. I think moving Copp back with Lowry helps that line tremendously. Having Little with Connor and Wheeler helps that line.
It is also why Morrissey looked much better when you put Pionk on his pairing today. With Poolman he was being asked to do it all, puck moving as Poolman is poor there and covering for a player who is in over their head defensively. The end result results is the team spending more time in our end. With Pionk he can at least move the puck quickly and gaps well in he nz so JoMo only really has to cover for him defensively. The team isn't defending as much and can press more. Morrissey also looked excellent with Niku in the preseason for the same reason.
Balance is a good thing that takes pressure off of your best players
Maurice also needs to manage the minutes of our top players. Hard to stay mentally and physically engaged when playing big minutes every game. The same is probably true of players playing too few minutes (Hard to stay sharp when you don't play much)
I think a more offensive style will help as well as the more time on the offensive the less time hopefully defending. Quick skating dmen that can hard gap with forward back pressure in the nz will force a lot of dump ins. With a mobile and active d that can quickly transition those dump ins back out of your end.
Also spending less time in our end will lead to better 5 man defense as there will be less chance of pulling a player out of position or a player missing a switch. Also less fatigue playing it.
I will have to look more at how we defend as a 5 man unit, perhaps we need to simplify the system.
I also think players will be more motivated to defend if they see the offensive benefit to it. The way it is now we generally have a hard time gaining any offensive traction after extended time in our end.
