The good thing is that the team should have more depth this season up front which will give Cassidy flexibility....and I love that he's willing to mix up the lines and use the carrot and stick approach instead of throwing the same stale lines out there regardless of performance. If you don't do what you're supposed to, then you sit.
I think the Kuraly Acciari Backes line is more playoff material than regular season. I don't think they bring enough offense to be a constant feature. But the fact that Cassidy has the choice of rolling them out there together to give the team a jolt is a great thing.
At any rate we should also have enough goals from Bergeron, Marchand, Krejci, and Pastrnak to get into the dance. Then if you roll out the big boys in April...and alternate them with two talented lines the Bruins will be really tough to handle.
