I don't think you know what you're doing when you say LeBron had "been in the league 3 years longer". You're actually aiding the argument for Bron.
Why? Do you know what college is to the NBA? It's basically the real D-league and back then way more than today. Have you ever heard the phrase "he should have stayed another year in college"? Do you know why people say that? Because the kid wasn't ready. A lot of boys get lost in the NBA. College allows players to mature mentally and physically and hone their skills. Especially at UNC. With Dean fukking Smith. The NBA doesn't teach you how to play. You're supposed to already know that when you get there. You're supposed to do what the game plan asks you to do. Simple as that.
By pointing out that LeBron was good enough at age 18 to not only play in the NBA, but play in the NBA at a high level just goes to show how ahead of the curve he really was/is. The fact that he was already playing in the Finals at the same age the GOAT was just entering the league only speaks to the brilliance of James and nothing else.
I'd also like to point out to Kobe stans that Bean also entered the league at 18 and compare his first year to Bron's.
Kobe won his first Finals MVP at the age of 30, his 13th year in the league. It should be and will be acknowledged that Kobe also helped the Lakers win 3 more titles as

's sidekick much earlier in his career.
