Detroit's top line has been every bit as good as Washington's top line this year so it'll be interesting (predictable) to see how Washington matches up with them.
I assume Orlov and Jensen will get the bulk of the minutes against the Bertuzzi-Larkin-Raymond line, but I fear Laviolette is going to throw out Hagelin-Eller-Hathaway every time Detroit's first line steps on the ice. In the last game against Detroit, the HDH line was matched against Detroit's top line and HDH absolutely smoked: they posted a 17% (Hagelin), 9% (Dowd), and 12% (Hathaway) xG% for the night. Meanwhile in the limited time Washington's top line was on the ice against the Larkin line they dominated the play to the tune of 80+% xG.
IMO it would behoove Laviolette to reduce the minutes of his "shutdown" line and spread the minutes more evenly with the McMichael line and the Protas line.
I'm sure there's a possession-based counter argument to this, but I assume you realize the reason for having a "shut down" line is you take a calculated risk that your defensive forwards will do enough to stop or slow down the other scoring line, which frees up your scoring line to have a better scoring rate vs the opponent's shut down line. This is especially necessary if you're a top-heavy team that can't afford its top line to be bogged down playing defense all game, and getting smoked by the other top line.
IOW the checking/shut down line is going to suck offensively but you hope they mangle the other team's stars while your stars get less mangled and score more.
If you think your top line is going to spend too much time playing defense against the other top line (or they'll give up more goals than they score) you want that checking line taking over that duty, and you try to slot your scorers on changes vs weaker matchups.
Now, if you have convincing proof (not speculation or mildly correlated stats) that show significant scoring advantage when you play nothing but offensive lines that could potentially be outgunned by the other team's scoring lines, they should be posted and then sent to Lavi immediately as that would change hockey entirely and forever.
Someone has to score fewer goals in every game unless we expect every contest to go to a shootout. So theoretically, if you want to win, you need to assess when you're at an offensive disadvantage and do something about it, otherwise you lose, right? The only way to stop that is some kind of EA cheat code that lets you stockpile the league's top scorers on every line, right?
