Yes, it's completely rational to judge great players by the factors out of their control: was the team that drafted them able to surround them with other all-time great players or multiple all-stars in their first 5 years in the league or not? This is why Jordan, Kobe, Duncan, and Curry deserve extra credit and Lebron doesn't.
The disconnect between the narrative about Lebron fabricating championship teams the easy way vs the actual quality of his teammates and how they complemented him compared to those other players is pretty staggering. AD is the first teammate he has ever had who was a positive fit with him and also a superstar. Wade in 2010 and 2011 was the only other teammate who was a top 10 player in the league...
And Jordan was not the best player from start to finish. He had 9 seasons where he was the best or arguably the best player. Lebron is at 11 to 14 depending on how generously you want to slice things up.
