Lbj isn't as good a shooter by any stretch of the imagination.
That's true..but he's better than then at certain parts of the game too. Bird was the best shooter of the 3, and the best passer, although I don't think LeBron as a facilitator is too far behind Bird.
Jordan is the best scorer of the three, but because of his athleticism, I don't think LeBron is too far behind Jordan.
As far as all-around talent, I think he's on par with those guys at age 26.
Whether or not he'll be remembered in the same light when his career is over though will depend on what he does or doesn't achieve in Miami.
EDIT: And also, if anyone thinks that Bird or Jordan would've done more than LeBron did if they had similar supporting casts at similar ages, you're just wrong. Feel free to disagree, but you're wrong.
