So he doesn't face the other teams top lines most of the time and he's a #1 RD.

Let's take these one at a time.
1. The Sabres first is still probably in the teens. They aren't a bottom feeder, they have a ton of talent coming, but there's some fair questions about goalie, bottom 3 d, #3 center, and defensive play from almost all of the forwards. Plus our division is still a gauntlet.
2. Not sure where you heard this narrative about Rosen, but it's uninformed at best, and frankly wrong. Comparing him to kulich who put up the best ahl season for an 18 year old in 30 years?- you're moving the goalposts to suit a narrative. The Sabres prospect guy said Rosen was the best player on the ice for the playoffs, and that teams were keying on him and making sure to hit him at every chance because he was so dangerous. I think he still needs to add more weight, but that's the worst I can come up with.
3. Yeah, I'm not a big jokiharju fan, to me he's a bottom pair guy that can move up in a pinch. He is however right handed which adds value. I feel like depth lefties are a dime a dozen, righties that can play just have more value.

Pesce turns 30 right after that extension starts
NO WAY Buffalo would trade for him with that contract

Pretty unlikely imo that another team would either


Now, if it was a 5year deal, then the Sabres could be interested
Including Carolina I’d suspect
The problem for u guys is that you’re not gonna get full value u less he’s willing to sign a more reasonable deal


Basically, if the deal he wants is too much, or too long for u guys to consider, why would any other team do it??


And besides the Sabres not being interested in Pesce with that contract, we surely aren’t overpaying like Caniac wants

ZERO CHANCE this deal happens- NONE

Zero chance he waives for buffalo so yea i agree very unlikely
