They’re typically not mentioned as the best over mj Scottie, magic kareem, malone Stockton and bird mchale. I think the primary reason is the regular season accolades weren’t great due to voter fatigue, team success, and injuries.
Curry was regarded as the best or second player in the nba after the back to back mvps, and KD was 3rd behind lebron after being the more recent mvp. They were both in their primes as top 15-20 players all time, fit seamlessly and had all the team success with the chips.
The two duos that are typically at the top are mj/ Scottie, and Kareem magic
Arguments against MJ Scottie, MJ is the greatest ever but Scottie was closer to the top 5-10 player during his era at his peak.
Magic Kareem: Kareem’s last dominant mvp year was magics rookie year. Definitely a longer stretch as a duo but for 2 year stretches, they didn’t win back to back titles until kareem was 41
Honorable mention is Cousy and bill but none of us remember that.
No as a duo give me shaq and Kobe. KD and Curry benefited from having the 3rd, 4th, and 5th players as Draymond, Klay, and Iggy. On top of that the bench was great the first year. Shaq and Kobe with that supporting cast would be disgusting.
