I agree with this unless the change you're making is inserting almost anyone for Jack Johnson. To me, thats always a winning move.
Smith OTOH did nothing but buy himself more ice time.
Also Georgiev should start tomorrow. Play him until he loses. If he goes 55-0, Shesty will have to deal with that.
When it comes to the D pairings, I think there's another consideration that likely supersedes the rest. Balance/Chemistry.
People assume if TDA draws in, Smith comes out. But I dunno if thats the best option. Both TDA and Miller should be paired with a steady defensive partner. They likely should not be paired together.
If you all noticed, the minute we paired Miller with someone who was more Defensive minded, he started to be more active and mobile. At times, he ran around. But he had more freedom to use his skillset -- skating, anticipation, rushing. Knowing he had someone more stay-at-home next to him he played far less tentative. We got to see what he's good at.
It's possible Miller may morph into a more traditional shutdown guy eventually. But right now I don't think that's his game. He's best when he's active and keeps those legs moving.
Letting him play this way may mean he's not learning all the positioning and fundamentals he needs to. So, there's a trade off here.
But point is, if TDA draws in, who comes out? And if both Miller and TDA are in the lineup, how can you balance the pairings? It's tough.
Maybe: Trouba Lindgren, Fox Miller, TDA Johnson. I don't think that's ideal for Miller or Fox.
OR: Trouba Lindgren, Fox DeAngelo, Miller Johnson? Yikes...
OR no Miller, instead: Trouba Smith, Fox Lindgren, TDA Johnson.
There's not a ton of good options with both Miller and TDA in the lineup. Really hard to balance the units. And really hard to find pairings where each player can play up to their skillset. When Schneider and or Lundkvist comes along the ingredients change. And I think for the better.
