It is also really odd that despite that line being on the ice for no goals, they still get the least ice time in the third, besides Sasha for whatever dumb reason. Everyone knew that line was not going to work well with Marleau, no matter your opinion of him this year, and yet that line still gets punished for doing pretty much what everyone expected.
Donato has been one of the most consistently good forwards this year, so I get why you might try to put him with Hertl to get him going again, but why then strap Marleau to them. He is clearly not a top 6 forward this year. Then on top of that Donato has a rough game, and instead of trying to get him back with linemates he is actually good with, or at least getting him on some other shifts in the third while you bench Hertl/Marleau, you punish him for your own dumb decision to change his line in the first place. NHL coaches really annoy and confuse me sometimes.
