Is the only reason lebron is so great because of his extreme athleticsm?

LeBron is a freak of nature. He is now and a few more years in his Prime. He is not a ball hog, but when his team is losing and he has 50 points, then hes starting to be a ball hog. I do not care for LeBron much but I cant deny he is amazing and his talents only make him better. With all that weight and muscle on his frame, his body will start to get very tired over the years and break down like the ones you named above. All 3 above still impact games though, and I can still see LeBron dominating, just not like he is today.
