Shaq was more physically dominant than Jordan so was Wilt. Doesn't mean they were better. I actually think that Lebron being this essentially "genetic anomaly" hurts his argument. Lebron has been sold as the greatest thing ever since he was a freshmen in HS. Jordan was nobody until his Sr year of HS and was never the no doubt physical prodigy Lebron was gifted with being.
Yes Lebron is a better passer but it's more of a focal point of his game than it was for Jordan. But Lebron wasn't so significantly better than Jordan at that. People act like Lebron is a passer like Magic when he just isn't to that level. Jordan was a better scorer and a better defender. Yes Lebron can guard PF's and C's better because of his size. But at guarding the perimeter Jordan was a better defender. Plus the 9 time 1st team all defense awards vs only 5 for Lebron says a lot. Also despite the size difference I am not convinced Lebron was as strong as Jordan was physically. Jordan in his prime was also a much quicker player and to me had the greatest first step in NBA history.
As a player Jordan's 7 year run from 86-87 thru 92-93 seasons he was the better player compared to any 7 year stretch from Lebron. The 1 year Jordan was able to essentially play PG like Lebron in 88-89 he was 32.5 PPG , 8RPG , 8 APG , 3 SPG , and shot 54% from the field for a 6'6" 200 lb perimeter guy that wasn't a great long range shooter. Not a 6'8" 250+lb perimeter player. But after baseball Jordan had to adapt his game to help with his longevity. Lebron generally hasn't had to change his game too terribly much because of his natural physicality. Though I think Lebron is more big and athletic than he is strong/powerful. Other guys in the NBA stronger than Lebron now. Honestly have wondered why Lebron has not averaged more rebounds over his career considering his size advantage he typically has over his positional opposition.
