You would be 'punting' with a Lindholm match-up as well, only you would keep an existing line intact that might have a chance to counter. Suter-Blueger-Mikheyev is purely to kill time.
I would also make Hughes and Hronek the Dpair to Suter-Miller-Boeser, as before, and have that 5 man unit follow up Joshua-Lindholm-Garland. Putting Soucy-Myers with Suter-Miller-Boeser instead may be why the unit hasn't worked.
To sum, roll out Suter-Miller-Boeser-Hughes-Hronek as one 5 man unit and then interchange with Joshua-Lindholm-Garland-Soucy-Myers.
If that doesn't stop them, it's going to be short series regardless.
Any line matched up against McDavid/Drai/Hman is pretty much just there to kill time. The job is damage control. That unit is a terror.
Like I said before, if you allocate pretty much all their best players toward shutting the EDM top line down, you're going to limit what they can create offensively. And the knock-on effect is that the rest of the lineup is so ineffectual the best you can hope from them is really that they just kill time too.
I don't know if it's the best alignment or not, but the point of my "punt" line, again, is explicitly that you hope they
can just kill time against the McDavid unit, which frees up much more favourable matchups and deployment for Miller and Pettersson.
