I've thought about Tuch as well. They're deep with wingers in Vegas, I'd love to see him pried away.
I think Krug is the one that needs to go out though, not Gryz. I love Krug but I don't see how they can add an expensive winger without sending some money out. Even with the dead money coming off the books and a buyout of Backes (that would save $2m) they're still only going to have around $5.5m to spend. Of course that depends on who they keep. If they let Gryz go, they'd have around $8.5 to sign Krug but not bring in a winger, unless that winger makes less than $2m.
