Why would expectations have anything to do with it? So because Lebron was expected to great, and he is great, that makes him even greater??
And if you want to talk about reaching levels of mythology, then I think the GOAT label can only go to one man, and it aint LBJ.
For the record, I really really used to hate him, but I have come to respect how great he is, I think Lebron is #2 all-time. Cant ignore the rule changes and what MJ had to go up against. Also, Lebron quitting against Boston and Orlando, faking the elbow injury, moving to South Beach, the flopping, whining, going out of his way to tell everyone how focused and hardworking he is (zero dark thirty for the playoffs etc), and how overall garbage the east has been for most of his career. Ok that's a pretty big list for #2...maybe i should reconsider...
