I don't disagree with that on either the Marner or Nylander fronts. I do think we overestimate the value of being balanced as a team though as well, overwhelmingly good in one place can make up for being bad in another, but if Seth Jones was available then I'd be listening for sure, I just think that guys on that level don't come available that often.
I think the way that our lines are built, they get a lot of synergy value from not just the talent level of the players but also the archetypes in each position - we're built to enter the zone through the RW a lot with very fast, high possession time RWer's who are fairly pass-first and can either beat the defender around the outside with speed or back them off with speed and turn back to give themselves space to make a pass. Our top 3 centers are all shoot-first, dangerous from within 15 feet of the net without having to touch the puck for long, and or LW's are able to get to the ring-around dump in from the RW and are good secondary pass options for the RW if he gets in clean because they can also score from in tight. Interestingly, Bracco is also very much that archetype of RW so we may have a replacement if we traded one of them or if Kapanen is moved to the left
Ultimately I don't think a team with Andreas Johnsson as it's best winger would be that offensively effective, but we might have some talent to spare on the RW with how good the centers are and if Bracco turns out
