Your close but I would say look at some previous NHL trades like this that happened in the past couple years.

More than likely, to get 22nd, you'd need to give something like what NYR gave to Ottawa last year to draft K'andre Miller. (26th+48th for 22nd)

In my opinion, you're selling yourself short. You drop back 12 spots in the draft (and out of the first round at that) and all you get is a late second? To move up a few spots in the late first round normally costs a 3rd, so I think you're not getting nearly enough for how far back you are moving. But if you are asking if the Devils do that, I think they do.

As a Devils fan, I would feel bad accepting this. LA could get a better deal than that for pick 22
