Don't get me wrong, I don't think he's an elite D man by any means, but he would certainly fill a need as a big, tall top-4 Dman. I might get flamed for this, but I'd even do Virtanen + Rathbone for him. Trust me, that wouldn't be as bad as the Hall for Larsson deal. But, he's a rare comodity that's VERY hard to find. It's important to note too that until Dahlin came around, Buffalo had these unrealistic expectations of him being their #1 Dman. Now that they have Dahlin, and a right side of Montour, Miller & Jokiharju, Risto is expendable for them - and I think he'd fit like a glove in a top-4 of Hughes, Myers, Edler (for now) and Ristolainen.
I'm also hoping that we find a way to sign Barrie (who I think will inevitably become a Canuck at some point), and then Briesbois, a guy who we've steadily developed, steps in and is ready to play. And then there's Tram, who I think will be signed once the cap is figured out.
Hughes - Ristolainen
Edler - Myers
Tryamkin/Briesbois - Barrie
And I'm not quite as sold of Rafferty as others are.
