That's an extreme overpay for duchene

I get Hamonic is a good defender but missed a ton of games last year, 14 points and -21 don't get you Eberle and 22nd overall. IMO Eberle for Hamonic makes sense but if more is required from Edmonton it'll be later picks/prospect.
I think it'll be more Hamonic to Av's for Duchene over Edmonton.

Yeah no thanks on the hamonic trade. Overpay.

Chiarelli offered taylor hall for hamonic last year and garth snow said no, you're gm clearly thinks hamonic is a very good dman just like he thought of larsson when others didn't (and was right), so garth isn't giving up a 3/4 dman with a very good contract and one more year than eberle's contract which is an overpayment. That first rounder is also late in the round in a weak draft class.
As for the duchene trade nelson and strome can both become expendable if you got eberle and are getting a forward back especially for cap reasons and again mid/late 1st round picks in a weak class paired with a prospect should also be expendable in order to significantly improve you're team especially when the team is trying to convince tavares who wants to win to sign long term.

If you want to make that trade for Duchene then Barrie must be in the deal.
