For me the 2 most dynamic player is Matthews and Marner. Nylander had a lot of succes with a East-West system where he had a lot of great succes but his best rate/82 game season under a north-south ( Babcock) system was not amaizing

The question i had its if nylander will be able to still producing at the same rate under a north south system and if Berube will still as much patient everytime Nylander taking a shift off in the defensive end. Personally Nylander is at my top 1 spot of playwr who could drop into the new system. There no fuarabtee at all than he will still as much dynamic in a different system. System will he benefot to some player but be negative to some player, it's always the case with any coaching change whatever wich team it is.
The first thing I said was "two best scorers", and I don't think anyone believes them to be other than Matthews and Nylander.
You may consider Marner to be a more dynamic player than Nylander (although I think you're in a small minority), but even if that were so, it doesn't change my point.
The north/south vs east/west argument is pretty weak, as he's one of the least east/west players on the team. And I'm not sure why you think a young player, usually on the third line (10th in toi per game), is comparable to an experienced one.
Nylander hasn't been "taking a shift off" as much in the last couple of years, and if there's any player who is likely to have more trouble in a north/south system, it would be Marner rather than Nylander.
