All first round picks aren't created equal, so thats going to make this difficult to judge.
In 2010, i'd have given up anything for the Oilers next 5 first rounders, but not much for the hawks (easy to say in retrospect, i guess). Alternatively, I wouldnt give you much for Oilers next 5, while the Canucks/Colorado on the other hand...?
Exactly as I see it. I can't see Edmonton with McDavid or Toronto with Matthews or Buffalo with Eichel being willing to trade their top players for first rounders no matter the quantity as these kinds of players are not always available in the draft. Yes 10 first rounders may produce 10 star quality NHL players but it could also be just a bunch or average players to a bunch of busts.
A single 1st round pick for Zetterberg.
