System has some to do with it, but I dont think changing systems is going to convert these guys into high goal scorers.
I mean just look at everyone on the offense, only a couple of them have only ever played under Torts.
Nobody apart from Nash and Cally have ever even approached 30 goals. (ignoring richards).
Compare to lets say the pens last year... They had what, 5/6 guys that hit 25 goals? And thats with crosby out of the lineup.
Who are these guys that are going to explode goals wise in a new system? Nash, sure. Who else? Is Hagelin going to score 20+? I doubt it. Who else? Stepan? Maybe. Zucc? Very doubtful.
This team, like always, is top heavy. It was much better in 11-12 with Dubi and Anisimov, but its never had the scoring depth to not rely on 2-3 guys. And next year wont be any different.
Can compare to a team like Stl, that has what, 7 or 8 20 goal scorers on the roster, but no real superstar. They beat teams by having everyone on that team a threat to score. Sort of similar to how Boston wins.
