This concept is rather new. I tried something similar in fantasy soccer for several years, and it actually worked quite well. Let's see if it works in fantasy hockey.

Basically, there are three types of stats: Goals (G), Offensive Points (OP) and Defensive Points (DP).

Defensive Points kill Goals.

(EXAMPLE: Team A is playing Team B.
Team A scored 3 goals and had 1 DP.
Team B scored 2 goals and had 3 DP.
Thus, all 3 goals scored by Team A were killed by Team B's 3 DP.
At the same time, only 1 of 2 goals scored by Team B was killed by Team A's 1 DP.
Thus, Team B won 1-0).

However, Offensive Points kill Defensive Points.

(EXAMPLE: Team A is playing Team B.
Team A scored 3 goals, and had 2 OP and 2 DP.
Team B scored 2 goals, and had 1 OP and 3 DP.
Thus, Team A's 2 OP killed 2 out of Team B's 3 DP. The remaining 1 DP killed 1 of 3 goals scored by Team A, so there are 2 goals left.
At the same time, Team B's 1 OP killed 1 out of Team A's 2 DP. The remaining 1 DP killed 1 of 2 goals scored by Team B, so there is 1 goal left.
Thus, Team A won 2-1).

Now, how do you get Offensive and Defensive Points? (Goals are pretty self-explanatory).

Well, the only way to get Offensive Points is by making assists. One assist = 0.5 OP.

As to Defensive Points, the only players who can get them are Goaltenders and Defensemen.

If you're a Goaltender, you get 0.1 DP for each save. But for every goal against, you are penalized: -0.5 DP. So you might want to keep at least .833 Sav% in order not to go negative.

And if you're a Defender, you get 0.3 DP for every block. That's it.

So, basically, 3 blocks and 1 save can kill 1 goal. Or 2 blocks and 4 saves. Conversely, 2 assists can kill said 2 blocks and 4 saves.

(Notes:
1.All OP and DP are rounded down. So if you have the total of 2.5 OP, it's the same as having 2 OP, not 3 OP. And if you have 3.0 DP, 3.1 DP, 3.5 DP or even 3.9 DP -- it's still just 3 DP, not 4 DP.
2.At the same time, the total DP can't be less than 0, even if your goalie had a horrible night and your defensemen didn't do much blocking).

Hence all real stats you should care about are goals, assists, blocks, saves and goals against.

Now, every game period lasts 2-3 days (with a couple of exceptions) and includes at least 15 NHL games. That will amount to 71 game periods in 2019/20.

During each game period, your team plays one game against a specific opponent and fields 14 players:

1 Goaltender
4-6 Defensemen
2-3 Left Wingers
2-3 Centers
2-3 Right Wingers

Basically, 1 goalie, 2 five-man units and 3 extra skaters (1-3 of which can be Forwards, but no 2 of those can play the same position). So you can determine your tactics for the game and even alter it during the game, depending on the situation. You might decide you need more or less defensemen, determine whether your defensemen should be offensive or defensive, and figure out whether you need goals or assists more at the moment.

(Note: Even if a game period contains 2 or more real games, you can't field the same player twice. Well, you can, but only his first game will count. Sorry).

And that's pretty much it. A game is over, whoever won gets 2 points, and if there is a tie, both teams get 1 point each.

Now, if two or more teams have the same number of points, the first tiebreaker is the total GOD (G + OP + DP) sum. Meaning 3.9 DP won't make more impact in this particular game than 3.0 DP would have, but at least those extra 0.9 DP won't be totally useless overall.

So in a nutshell: the stats will be quite easy to follow, but at the same time you'll still need to be quite active. A game every 2-3 days (not once per week), new tactics for every game (and sometimes you'll have to change it in real time), and a fairly balanced roster.

If anyone is interested, I'll add more details regarding software involved, season structure and keeper rules...
