Guys like Callahan, Hagelin and Stepan are secondary scorers. Those guys need to score regardless of who is on their line.
Hags looked good last game. With the energy he brings he'll get on the score sheet consistently. Stepan is quietly putting up points. I will never worry about Cally. His game obviously is so much more than what you see on the scoresheet.
I still think these lines are best suited for balanced scoring:
Nash has proven throughout his career that he doesn't need elite line mates to produce. He can create offense on his own like we have seen in the first 3 games. Putting all of your eggs in one basket will work some games like yesterday but isn't a good strategy over the course of a season. These lines have the added benefit of every player playing in their natural position. Gabby looked MUCH more comfortable yesterday back at RW.
