I'm not so sure I'd prefer Acton to Lander. Yes Acton is more noticable and is in on the forecheck more, hits more and gets involved slightly more offensively although I doubt any of those two guys reach 15 points in the regular season.
But he's struggling to keep up defensively, he was on the ice for all three goals against vs NYR, one of which he was directly responsible. Lander is not adding much but he's solid in keeping things at bay in his own end. And for me the number one thing for a 4th line, at least when you have a so so 4th line like we're going to, is to not bleed goals.
I have a feeling that once we start to play real games with all the other teams bringing all their offensive players Acton is going to be a huge liability in his own end. He puts himself out of position and isn't quick enough to get himself back. At the same time the primary thing Lander is good at is defensive positioning. And since we're not going to lean at our 4th line for scoring goals I have to say I prefer that.
Having said that my guess is that Acton sticks and Lander is sent down. I believe Eakins wants his players to be more noticable and make more noise on the ice a point I can sort of understand but not fully agree with.
Edit: and there you go, Eakins went with the noticable guy. Hope he's right.
