I wouldn't be opposed to putting the SOB line back together. The problem is it makes the third line much weaker. If the SOB line goes back to playing like they did last year, I think it may be a moot point. If we decided to do that, I imagine the lines would look something like:
Schwartz-Lehtera-Tarasenko
Steen-Oshie-Backes
Berglund-Stastny-Lindstrom
Ott-Lappiere-Reaves
I honestly don't see that as a problem. If the SOB line returns to the form we know it can perform at, that's a ridiculous top 6. And a very good 4th-line.
Who cares if the 3rd line is weaker? Seriously, at this point who cares? Stastny and Berglund are still good enough defensively that as long as they aren't getting scored on a ton, it shouldn't be a complete abomination. And they shouldn't be getting scored on that much. Plus maybe Stastny can make Berglund score a little more. It's worth a shot.
With Berglund being who he is, and a hole on the right side - whether it's Paajarvi or Lindstrom - we're not going to have all 3 lines in the top 9 firing on all cylinders. I just don't think it's going to happen. You can keep mixing and matching all you want but that's not really going to do anything. Lindstrom, Paajarvi and Berglund are who they are... right now, that being the weak links. Berglund less so than the other two but my point should be clear.
It's really no different than any other season. There's always one or two lines that carry the scoring. If we had all 3 lines dominating we'd be scoring 4 goals a game and winning every game. That doesn't happen in the NHL. Players will struggle, and other teams aren't cakewalks.
