Think he is a Ferraro caliber player. Realistically, think a Ferraro-Fabbro 2nd pairing is pretty decent, probably average to above average (which is a big step up from where we've been this year and the bulk of the last few years without EK65).
I don't want to pay a steep price for him, but if you could get it done for a Wiesblatt/Coe/Robins/Guschin + 3rd type of a deal then I'd be into it assuming you can get a reasonable extension signed this offseason for 2-4 years (not sure what his RFA/UFA status would be after a 2 year deal - if RFA after 2 then 2 year deal, if UFA after 2 then 1 year deal to RFA or 3-4 year deal to buy up UFA years).
