This is tough because some pairs I feel have only individual "iso" ability or others have strong duo "chemistry" giving assist to each other. Few have "both" strengths. I'm still do top half so 11 and note what I feel they have strongly, if "iso, chem or both"
For the record though I'd say healthy Curry and Klay would be top 4 for me if they were in the bubble.
1. LeBron, AD (both)
2. Giannis, Middleton (both)
3. Kawhi, PG (Iso)
4. Harden, Westbrook (Iso)
5. Butler, Bam (Chem)
6. Siakam, Lowry (Chem)
7. The Js (Iso)
8. Luka, KP (Iso)
9. Ingram and Zion (Iso)
10. Lillard, CJ (Iso)
11. Embid, Simons (Iso)
I can explain my veiw on each in more detail but trying not to make too long a post. We all have our opinions.
