I don't judge it by that. Thats always opinionated. Almost always circumstantial.
I look at the overall body of work. I look at circumstances. I look at strengths and weaknesses.
Lebron is similar to Shaq that their physical gifts make them seem like a lock for 'best ever', but in both cases, something was missing.
Most of the second-tier legends, I feel, have first tier abilities/attributes, but whether through circumstances within or beyond their control, they didn't ascend to that level.
