There seems to be some confusion about a player playing center and a player being the first forward entering d-zone while opponent is on the rush.
You're the one who seems to be confused.
The way the Eichel line plays, it naturally leads to Eichel NOT being F1 on the backcheck/defensively quit often. Which naturally puts one of his wingers in to the Center role defensively. This is HOW that line is playing. It's designed/coached to play that way.
Reinhart having center assignments on d-zone on several occasions was pretty much the same thing that Girgs did with Eichel as well.
Correct, this is how the Eichel line is designed to play. And has been since early on when Larsson was on that line.
Eichel tends to play pretty deep and take chances on the o-zone. That more than often means that he is not the first forward entering d-zone.
Correct, this is how the Eichel line is designed to play.
The basic duty for a forward who comes after two d-men on d-zone is to cover the third, lone opposing forward - no matter the position you play.
Correct
And you DON'T change the positions if the opponent has the possession unless there is a CLEAR opening.
Correct. So as we've now established... Eichel is playing an aggressive and deep attacking offensive role, leading to him more often than not NOT being the F1. Thus making his wingers responsible for taking the centers role defensively (unlike other lines center responsibility falling on... you know, the center.)
I didn't see Eichel and Reinhart changing positions if Eichel was the first forward on d-zone.
As you've already established, Eichel is not always the first forward in the d zone.
If the line was designed to have Reinhart having those assignments, they would have switched positions.
The line IS designed to make that switch... as we've now established.
BUT there were situations where they could have switched positions (Reinhart becoming a winger), but they didn't.
There were, and they did.
That alone doesn't mean there was some integral design. On many situations Eichel had the center assignments
When he's F1
He's F1 in fewer cases, because of the design of the attack (based on his natural ability)
It was pretty clearly designed that way (as you noted with Girgs before him). And with players like ROR/Reinhart paired with a player like Eichel, you will continue to see it. Eichel will continue to play high defensively when he's not F1, and he will continue to be puck dominant down low offensively. That will continue to produce F1 responsibilities for players like ROR/Reinhart. They will effectively be playing the center responsibilities defensively much of the time if they are on Eichel's wing.
To pretend this is not by design is naive or intellectually dishonest. your choice. The difference is that when you see it from Girgs, the outlet/playmaking/vision does not support the breakout the way a guy like Reinhart can.
Generally it isn't optimal way to deploy you're line that a winger has center assignments on d-zone and the center is the primary puck carrier. And the reason is that as soon as you get the possession on your own zone, you want the puck as fast as possible to your puck carrier to the middle and to the speed.
It's perfectly normal. See Briere/Hecht
And The puck gets to Eichel as fast as possible, when Reinhart is the point of transition
If your center is presumably standing next to a board when you get the possession, it takes a decade to organize the rush as it should be organised.
No, Not when that player has wheels like Eichel. You should cease with silly generalizations when it comes to Eichel.
And if you want one of your forward to be the puck carrier from center ice wihtout having defensive assignments of center, you just put him as a winger. Just like Tyler Ennis played last year. Or was Ennis and Larsson/Girgs splitting playing center? Of course not.
Which was how Eichel was utilized when he was not F1 on the backcheck. Also, transitioning through center ice, presents opportunities for distributors/playmakers. But transitioning down the outside, is just as aligned with Eichel's blazing speed that creates mismatches.
And that is also a reason why Eichel should be surrounded by defensively sound wingers. You don't want Eichel to play safe and sound on o-zone - you want him to use his skillset. And if he has defensively sound wingers, he doesn't have to worry about being the first guy back d-zone.
When he's not the first guy back, he's not playing center. period. its not even debatable. That's a choice of scheme/strategy. and it was employed last night. and practically every night since the Larsson-Eichel pairing, through the Girgs-Eichel pairing, to the recent Reinhart-Eichel pairing. The "mixed" usage strategy allows Eichel to NOT play safe and sound. To be the puck dominant offensive player, without any weaknesses around the net/premier scoring areas defensively.
Girgs and Larsson were used in the same manner, but did not provide the necessary transition skills. Reinhart does. ROR would.
