Impossible to replace a player like Weber, Letang, Karlsson, Carlson, Hedman and Seabrook.
The others are very good as well and be a gamble for a GM to trade Subban, OEL, Subban, Larsson for the #1 because these guys have had success in the NHL.
I voted Mark Streit because I would for sure trade him regardless of my teams positioning... also perhaps Kronwall too (even though he is very good)... the others it's tough to say espically without knowing personal team prospects/defensive depth... For instance I doubt Chia from Boston would trade the #1 overall for D. Hamilton in a 1 for 1 trade.
The team with the garaunteed asset is taking most of the risk here... they could look really smart or very stupid pending how the #1 pick turns out.
I agree that there is risk in trading for a draft pick, but #1 typically holds less risk when it is a forward. It's been a long time since a #1 forward has busted and the list of very good forwards is impressive. Also to take into consideration is the lower cap hit for 3 years, and having someone's rights for 7 years is also a bonus.
With that being said, will Yakupov be very good this year and be much of a positive contribution? His offence MIGHT be good, but rookies usually have issues with the little things and defensive play. There is the Russian factor, although I think it is very small with him.
Also with Weber, is Nashville willing to lose Suter and Weber for possibly nothing? While they may trade Weber next season if he won't sign long term, will the return be better than a #1? What if they are one of the better teams next season again and Weber won't sign? Do you risk losing him?
Lots to consider if you are the team giving up the asset though.
