As long as you are able to fit everyone in your lineup when they play then positions don't really matter. The only concern would be if you had players sitting on your bench wasting their games cause they cant fit into one of the open lineup spots.
Here comes a wall of text haha... And this applies for anyone reading this thread in a points league for fantasy sports!I'd say that Luka, Dame, Nurkic, Valanciunas, and Shai are your 'untouchables' at this point
Tier 1 - Luka and Dame are your building blocks. Top 15 talents.
Tier 2 - Nurkic, Valanciunas, & Shai - Top 20-40 type guys. 2nd, 3rd, 4th round draft picks. I would only trade these if you were getting back a top 15 type player (like Bam, Embiid, Sabonis, KAT) for one of them plus a lower level guy. Maybe combine 2 of them to get a top 5 person like Giannis or Harden but that's tough.
Tier 3 - probably Middleton & WCJ, solid depth guys that you start every night. Should be Top 40-60 ROS.
Tier 4 - Trez, White, Keldon, Bazley, & Oubre. All of these guys should be top 80-100 players and potential to be top 60-80.
This is where I would try and package 2 of these players for someone you feel would comfortably be top 40-60. Some ideas are Siakam, Mitchell Robinson, Ayton, Brandon Ingram, Zach Lavine, Donovan Mitchell, Fred VanVleet, Gordon Hayward, And John Collins.Tier 5/Streamers - Williams & Batum - I think you've got the right approach here, Batum is purely a streamer that you can drop and churn that spot for 5-7 games in 7 days if needed (use b2bs to get more value per add) and Williams is a stream that you maybe hold for a week and see if he becomes a starter.
The key is to constantly look for ways to combine 2 players in any tier and get a player in the Tier above.
If you were to do something like Harrell & Oubre for Siakam. That essentially 'upgrades' Harrell to Siakam for the price of 1 Oubre, and you now open an extra roster spot for streaming and can maybe move Williams up into Tier 4.
Think about it from a math perspective (using the basketball monster projections for your league settings):
Harrell=
25 fppg + Oubre=
24 fppg x
4 games each (on a good week) =
196 fantasy pointsSiakam=
30 fppg + Stream Spot=
~20 fppg x 4 gms for Siakam & 5-7 gms in stream spot =
200-240 fantasy points Let it ride
