Siegenthaler would be staying if that’s the offer
He’s worth more
Plus Devils would want to keep him for the future. They would part ways with Graves before they would sign Siegenthaler

I don't watch many devils games but is Siegenthaler outperforming Graves? and if Graves was on the market what would his asking price be?

Not him but, Graves has been great, Siegenthaler fantastic, so yeah I guess outperforming Graves in a sense.
So devils paid a 2nd a B prospect to acquire Graves so EDM would have to improve on that by some margin.

Barrie doesn't need Buffalo, he's not the type D we're looking.

Siegenthaler has been better than Graves on most nights. Siegs currently leads NHL in defensive Goals-above-Replacement and his partner, Severson, is #5. They have developed into our top-pair (and would likely remain so even if Hamilton were healthy). And usually lead team in TOI.

Smith has had up-and-down sophomore season, so has been third pair. Graves could potentially be move at deadline if Smith gets a little more consistent and/or they view Bahl or Okhotiuk as ready for call-up.

But it’s doubtful we move any d-man. Maybe Subban.

So maybe something simiar to the mayfield trade?

That might be right, but Buffalo needs RD. If not Buffalo there are teams out there that want him. Trading a pick in the late 50's to early 60 range shouldn't be a problem for teams as they still get and NHL dman back.

Why do you hate 2nd round picks??

But going forward in the future, the team wouldn't have the space for all of these guys, and it's clear that NJ won't make the playoffs this year. But the sense I'm getting from NJ fans is that Graves would go before Siegenthaler. And for relatively the same package as what you guys gave up for him right? I assume NJ would have to trade one of their LD as Smith will definitely be improving for majority of his career. I know Siegenthaler is a hidden gem in this league which is why I made a mock trade for him but I still like graves as well. If a 2nd and Lavoie would do the trick I would think it's a fair deal.

Which Mayfield?
If it's Scott Mayfield you thinking of I don't recall him ever getting traded.

The perfect trade value to grab a rental who isn't a star

lol sorry, I meant my Mayfield mock trade

Np.
And I'd be very disappointed if that was the return Devils got for Graves.

Siegnethaler - not happening
Graves - wait a year

Devils gotta wait until some the kids show up before we move anyone.

Graves has been better offensive but Siegenthaler better defensively. Graves got traded for a 2nd + prospect. If the Devils trade him, it would be for a 1st+ or young player that fits the Devils timeline

Then I’d suggest sending him elsewhere. Barrie is everything we don’t need in a defenseman. We already have a PP QB for both PP1 and PP2

Buffalo is looking for RHD, but they are looking for more Defensive Defenseman, therefore I don't see Barrie being a fit here either.
