LeBron James - Is He a 19 Year Old?

When you're 18 years old and you come in the NBA, you're often like a different dude by the time you get to June. So I'm really focusing on how good I think these guys were if we had to stop the season on April 5th or whatever. On these playoff teams, it's going to be able to play at this level. That's the criteria I'm using to try to sort out the best young seasons in NBA history.
