I think there's some muddled thoughts in terms of "1st line, 2nd line, 3rd line"
Bylsma ****ing loved Staal. Staal played 19:30+ ice time a game (Crosby and Malkin both got 20+ minutes a game) from when Bylsma started as head coach.
Gotta think Girgensons is going to take that defensive heavy lifting duty over almost immediately unless we decide to get someone via UFA.
I think what we're going to see is a top heavy offensive line (Kane-Eichel-Ennis), a defensive heavy lifting line (Foligno-Girgesons-Gio/UFA/Trade), and a secondary scoring line with Moulson-Grigerenko/Larsson-UFA/Hodgson/Gionta/etc on it.
I see the more traditional approach with top 2 lines being scoring lines and the 3rd line being the 2-way, checking line. Reinhart's been lauded as being intelligent defensively and good on faceoffs but to spend time on 3rd line would waste the offensive creativity he has over Larsson or Girgensons. Finding a playmaker to get Moulson back on track is important IMO - Ennis alone can't do it and Girgensons as a # 1/#2 center is demanding more than he's really qualified for. While Z has some nice speed and 1-on-1 skills, he lacks the vision to construct a play or find open teammates through a crowd and he's not the best finisher either.
So, if the ROR dream comes true, I'd lobby for:
Kane-Eichel-O'Reilly
Moulson-Reinhart-Ennis
Girgensons-Larsson-Gionta
If Sabres don't add O'Reilly or a top 6 winger:
Kane-Eichel-Girgensons
Moulson-Reinhart-Ennis
Foligno-Larsson-Gionta
To those who think 3 young centers 22 or younger is recipe for disaster, I'd counter that they're surrounded on each line by established veteran support and no one is expecting the Sabres to not take some lumps on the learning curve next season. I think Reinhart will prove to be ready as will Eichel - and Larsson's already shown he is.
