This is the list.In my opinion (no order)
Magic
Jordan
LeBron
Bird
Kobe
For older generations, obviously Jordan. Then Magic and Bird will be on all of their lists as well.
Younger generations all know Kobe and LeBron.
The next cut would be Curry, Shaq (was huge in the 90s but his popularity waned a bit as his career did and he team hopped) and Iverson.
