FWIW, you don't need elite 80+ point players on your first line if you have quality scoring depth throughout your lineup and from your D.
Just look at the Bruins. Their top 5 scoring players are Krejci, Bergeron, Iginla, Lucic and Marchand with 69, 62, 61, 59 and 53 points receptively. And their D had Chara and Krug both at 40.
This is why I keep telling people to look out in ~ 2 years. The twins will still likely be ~70 points, Kesler and Burrows ~40-50 then you add in the likes of Horvat, Shinkaruk, Jensen and Kassian who should be putting up decent 40+ points. They're positioned to be a pretty deep team with scoring on multiple lines moving forward.
