Tyler Dellow of The Athletic wrote an interesting article based on Eric Tulsky's model on the cost of trading up in the draft.

He only looked at the 5 Canadian teams; Montreal - 3rd, Ottawa - 4th, Vancouver - 7th, Edmonton - 10th, Toronto - 25th, (Calgary and Winnipeg don't have a 1st round pick in this year's draft). Detroit were mentioned as a trade partner for all five picks.
According to the model and what Dellow sees as fair value, we'd have to give up the following to move up for each pick...
3rd overall - 6 and one or (more likely) two of 30, 33, 36
4th overall - looks like a typo in the article, but I would assume similar to the 3rd overall...
7th overall - 30, 33, 36 and 67
10th overall - 30, 33 and 36
25th overall - 30 and 67
I've already said that I'm against trading up from our 6th overall, but trading up to add another top 10 pick (7-10) really intrigues me. This model is based on draft picks only, but what would it cost if we added a player / prospect / pick(s) in future drafts? Based on the two trades involving the 7th and 10th overall picks, would Athanasiou, Vegas' 1st round pick or Ottawa's 2nd round pick, plus the Islanders 2019 2nd round pick be enough? Fair value for both sides? Too much? Not enough? I'd personally love for Holland to pull off this sort of trade to get both Bouchard and Wahlstrom. I think (hope) Holland will be aggressive, but I doubt he pulls this off...
