Pettersson is the guy I dream about that is maybe, possibly available.
There were rumblings from Michael Russo of The Athletic that Pettersson would want to move on. Russo would be a weird person to start an unfounded rumor about a Canuck player given that Russo is the Wild's beat writer, so I tend to think there is some truth to it. Vancouver also played hardball with Pettersson during his last contract and forced him to take a bridge so I could see that making him sour a bit on Vancouver. On top of, you know, Vancouver being a directionless franchise.
That being said I don't think Kuzy + #8 overall does anything to even begin a conversation. Washington would need to add a lot more futures, or get another team involved in a 3-way deal with a guy like Wilson going in the direction of that third team to even begin discussions. It's certainly something Washington should pursue, but it'd be complicated and cost a lot.
