About the who are our top-6 centers topic. I'd really prefer to find a way to keep all 4 of our high caliber players as wingers if possible assuming that Rantanen comes. If I'm not mistaken, Teräväinen has played most center of these players this season? He would be the first guy I'd consider moving to center if that was indeed the case.
Actually, it's been Aho. For the most season, the duo was wingers to either Staal or Lindholm, but when they were in a line without either, it was Seb who would move down the middle. And that's why I'd be wholly comfortable with him as our nominal 1C, especially with TT complementing him.
I wish Koskiranta or someone would appear out of nowhere to help in this center situation or some of Koivu, Filppula, Lehterä. I know about Filppula's and Lehterä's contract situations but still. Even Jarkko Immonen would be god sent now.
We can forget about Filppula, he has already declined. But Lehterä has no contract issues, he's got a year left.
Some speculation follows...
If we get Lehterä AND Koivu, building the top-six becomes kinda trivial. It should be:
Aho - Lehterä - Teräväinen
X - Koivu - Granlund
Plenty of options for X. I'd personally use Pesonen. He has played with Granny before.
EDIT: I mean in the absence of Rantanen, naturally.
If we get Lehterä but no Koivu, then:
Aho - Lehterä - Teräväinen
Pesonen - Suomela - Granlund
Suomela is good enough to be 2C, if absolutely no other options pop up.
If we get Koivu but no Lehterä:
X - Aho - Teräväinen
Pesonen - Koivu - Granlund
Rantanen for X would still be the no-brainer. But in case we don't get him, hmm... I'd use Peltola.
No Koivu, no Lehterä:
Peltola - Aho - Teräväinen
Pesonen - Suomela - Granlund
Of course, this is the likely scenario where Marjamäki will be tempted to just put Granny with the Carolina boys, but I am kinda hoping he'd try this instead. Let's keep in mind that in 2016, K.Jalonen put together a line of Aho - Koivu - Granlund, and that didn't work at all. So I have valid reason to merely "hope" TT - Aho - MiG would click, instead of being certain of it. Three playmakers in one unit is never ideal. Two can work just fine, but then you need some kind of power forward or a sniper complementing them.
In the case Rants is a no-show, one outside option would be to make do early with some kind of substitute and wait calmly until Preds - Jets is over. No matter the outcome, it could bring the possible relief - either Eeli or... Big Bad Pate. Even though I don't really dare dream of the latter. He could be pretty gassed by then.
