IMO, the shittyness of the 3rd line is direct reflection of how important Lundy is to this team's future. He's never going to put up the points like Leo or Z, but that 3rd line is a black hole without him.
As for Z - i like how he has responded to benchings and teaching moments so far, both this yr and last yr under Eakins. Big thing now for him is to realize to become a professional in this league, he should be working on holding himself accountable, and not have to wait until the coach gives him the riot act or staples him to the pine before he reverts back to a complete game.
Honestly, Gaucher is my hope for that 3rd line. I think Lundestrom is pretty bad too. I know he's still young, but Lundestrom is already a non-prospect for me. I think he'd be fine as a 4th line center with a couple of big wingers, but his lines get caved in regularly. The glimmer of hope is that he's played under Eakins his whole career and he's mostly been stapled to the slowly decaying body of zombie Silfverberg. But it's only a fool's hope.
Back to Zegras, that game last night told me a lot. He didn't score, and there were some frustrating moments when he and Terry had opportunities to create offense and weren't on the same page, so it would have been easy for him to check out or do his own thing. But he kept going hard, on both the forecheck and the backcheck, and was instrumental in that comeback. There will be moments of immaturity from him I'm sure, but if this is how he responds, we can live with that. And I expect they'll be less frequent as he ages.
