I agree that it's ridiculous but you're not going to get fair value for EDM. As I said earlier, you're trying to make a quantity trade for a guy who's not being shopped from a division rival. It's not going to happen without a ridiculous overpay. The price for a bonafide #1D at 5m AAV for the next 4 years is already steep even without factoring the circumstances.
Also, value-wise the Ducks are getting a 2C, two #4-6 D, a promising prospect, and two 1sts. It's a lot coming back but too much quantity and not enough quality so I still don't think they go for it.
Long story short, we've probably never seen a trade like this and we likely never will because the Oilers would need to gut their team to do it.
