Nah, hard disagree. Ain't no asterisk. It's definitely true that LeBron didn't spend those four years in college, but he's still going to pass Kareem in 150 fewer games. That's basically two whole NBA seasons. So unless you expect me to believe that LeBron wouldn't have still eventually passed Kareem if he'd went to college for two years, instead of going to the league straight out of high school, you can keep that asterisk, sir.
And that's no shade to Kareem, by the way: in my personal record book, Kareem Abdul-Jabbar is a Top 3 basketball player of all time, and he ain't Number Three. I just don't think that we need to diminish LeBron James to remember how great Kareem was.
