LeBron/Durant/Kobe/Dwight 1st quartet to make All-NBA 3 straight years since Barkley/Jordan/Magic/Malone ('88-89 - '90-91).
Which raises the question...who ya got? LeBron/Durant/Kobe/Dwight or Barkley/Jordan/Magic/Malone?
Definately out of your two it would be Barkley/Jordan/Magic/Malone. They were all unstoppable at a time when basketball was hard stuff. People forget how bloody dominant Barkley and Malone were, and we all know the GOAT would single handedly account for anyone he played on.
