I started a test game with the default rosters last night (no changes other than unfaking all the names). I agree that there are some very smart/fun systems in the game. If the AI is actually able to manage the cap and construct plausible rosters then it's close to surpassing EHM and FHM in terms of what I'm looking for in a hockey management sim.
My biggest pet peeve initially is the lack of nuance in the rating system. In the default DB, the best forwards are also the best defensive forwards. Connor McDavid, Leon Draisaitl, Nikita Kucherov and Artemi Panarin are all going to be perennial Selke contenders. Maybe BK's DB will be better in this respect, but with only 9 attributes, it may be a necessary evil to get players like McDavid to 98 or 99 overall.
Re: scoring, here's some very quick and dirty analysis from my sim:

We are definitely missing some top end scoring. This may be a ratings problem - I'm not sure if adding more separation between top end players and the rest would solve this.
