According to you, all draft picks pan out. Not that easy.
We need one of Lehkonen/Collberg/Andrighetto/McCarron/Thomas to become 1st RW. Possible, but may need trade/UFA. Max Pac - Chuckie - XXXX
We need one of Bozon/Hudon/Macmillan/Reway to be 2nd line LW. Possible, but may need trade/UFA. XXX- Eller - Gally
Third line as no proven component yet, but Leblanc will almost surely be NHLer, so we need Bozon/Hudon/Bournival/Vail/De La Rose/Andrighetto/Grégoire/Nattinen for LW and C/RW (whatever Leblanc isn't). Almost sure we can fill that line.
Fourth line already has Dumont and White, so either Crisp/Quailer has to make it to fill it.
D already has Subban and Emelin as top-4, Diaz as top-6. Tinordi is surefire top-6D, maybe top-4. Beaulieu is almost sure to be at least top-6 D. We need Nygren/Ellis/Bennett/Thrower/Pateryn/Dietz to fill a top-2 D, maybe a top-4 D and a spare or 2. Top 2D will most likely need UFA/Trade, but the rest can probably be filled with what we have.
Goalie has Price for 1st and unless something weird happens, one of Fucale/Tokarski/Mayer/Delmas will at least become a reliable back-up.
So no, we don't have a surefire line-up, but we have a lot of prospects for the holes we have.
