Personally I think that Dats, Abby, Alfie could play the Bergeron line even. I also think the Kid Line would give the Krejci line fits because of it's speed and because Sheahan and Jurco are the biggest and strongest options we've got to play against Lucic and Iginla. If we could get a wash out of those two and free up a Franzen, Legwand, Nyquist line to play against their third line, I think we could beat them. And it goes without saying that Miller, Helm, and Glendening would eat their fourth line alive/provide for defensive relief with defensive zone starts for the kids/augmenting the Kindl-Lashoff pairing.
If Dats and Alfie can play like Dats and Alfie (or better yet even, slightly younger versions of themselves) I'd say so, and Abby might be able to keep the worst of Marchand in check. The speed of the kids probably would cause some problems, I just don't think they have the defensive chops to keep up. If they got enough help it might work. Mule-Leggy (or Helm)-Gus should be able to beat their 3rd line.
No matter how we juggle the lines I think we should be able to get the better of their bottom 6. So if we can beat or break even with their top 6, it should offset their advantage on defense. Then it's a matter of Jimmy vs Rask.
Typed out, that last line looks more disheartening than it does in my head.
