I really like those lines, if its the versions of Backes and Oshie we saw last season, with the Berglund we've seen this year. Even the 4th line, I love.
If the Blues can't win with that line-up, I don't think there is some other juggled version that can do it either.
Today, Jaskin is an upgrade on Oshie as he's been up to this point of the season. I expect that to change, but right now Oshie's absence isn't really degrading the team much. I hope he comes back feeling hale and strong. Even if he's out a month, I'll live with it. It would be a good development for Jaskin's growth, for a silver lining.
Paajarvi...I can't fine where he fits in. He isn't nearly so bad as his minutes make it look, but there's noone anywhere along there that he's displacing. The only real move I could see would be Jaskin up and Lindstrom scratched. But that requires moving someone or waiving someone.
