Also, at defence, Tampa has been using 4 righties, because they have their best defenceman on the left side. Usually those righties have been average defencemen like Rutta, Bogosian, Foote, Schenn, Shattenkirk etc.
Sergachev and Hedman were carrying them, Just like Lidström did carry all Olaussons, Liljas, Whites and Woolleys on his era at Detroit.
Red Wings defence is already built, like a mirror image, of that Tampa system. RD Seider can handle the high minutes. Could be double-shifted.
Tampa did double-shift mostle Hedman. Sergachev got some shifts after special teams situations, if Hedman had already had a long shift there. But if they rolled many shifts in-a-row 5-on-5, it was only Hedman, who was double-shifted.
This is an example from the past season, not from the current Tampa core:
Hedman LD -- RD Rutta
McDonagh LD - RD Cernak
Hedman LD -- RD Schenn/Foote
Sergachev LD - RD Bogosian
So Hedman went with the worst partners, carrying them. That did give you strength on those pairs and let quality depth on other pairs, in McDonagh and Sergachev.
Red Wings "accidentally" has extra lefties now, as Tampa had extra righties. At some point, they are gonna start double-shifting Seider and going with 7D. For me, it's quite obvious, they are preparing for this. Lalonde is talking about it. He was one of the creators for this at Tampa, and Yzerman has been hoarding the players.
Also Jeff Petry has handled guite high minutes in the past, he can maybe take 1-2 shifts more. But it will mostly be Seider, because he has that natural stamina ability to go for highest minutes, maybe higher than any other NHL defenceman with Makar. We haven't seen that yet, but draft combine reports and some articles about his talent in bicycling athlete, will point on that direction.
So here we go:
Walman LD - RD Seider
Chiarot LD - RD Petry
Määttä LD - RD Seider
Gostisbehere LD - RD Holl

What makes this an effective way of defence, your left side defencemen are always behind the same forward lines. So you are starting to have more 5-man units, like at European hockey. It gives you better chemistries, when the D-pairs aren't changing behind the forward lines all the time. It also cumulates in a positive way.
And also, you double-shift your best defenceman, your best player Moritz Seider. Doesn't sound bad for me.
These things did made Tampa a best contender for a while, until the raising salaries after success did start to eat their cap.
