The only guys I'd be hesitant to give up are Kessel and Rielly. Other than that who on this team isn't worth losing to get Ryan Getzlaf. What on this team wouldn't you trade for a 27 year old Mats Sundin? Is there anything? I wouldn't give up quantity, but I'd give up quality. Nothing stupid like Phaneuf, Kadri, Grabo and Gardiner or whatever. But I'd give up any of those guys in a deal.
A deal based around Phaneuf could maybe. Throw in some pieces on either side to make it work. You would have to be able to get an extension first though. It would hurt, like losing Clark hurt, but in the end it'd probably be worth it.
