Well, I'll post this to help out. Note that all these players could be upgraded by better players offensively and/or defensively but it gives you a realistic picture of the organization chart. Dzingel and Stone are still there but they could probably be gone soon too, as well as several vets in the near future (Ryan, Smith, Pageau, Tierney, Boedker, etc). I didn't bother to list AHL vets or prospects with no NHL potential (Burgess, AHL, etc)

Major needs for me are (and would influence my drafting) :
1) Center with high end potential (2020 draft), can't put all hopes Logan Brown.
2) RD with potential, can't put all hopes JBD.
3) Good 2-way forwards for the bottom-6
Outside of that, I'd try to hit homeruns with my picks.
