Just looked up some info on Kareem and man is he underrated.
Greatest high school player of all-time. High school record: 79-2 (in New York)
Greatest college player of all-time. Back then freshmen weren't eligible for varsity so he could only play 3 years.
In the 3 years he could play varsity:
Record: 88-2
3X NCAA Champion
3X Player of year/Naismith award
3X NCAA tournament MVP
3X First team All American
Then, on top of all this, he goes on to be arguably the greatest NBA player of all-time.
Overall, if you want to crown LeBron GOAT you better first convince me he is better than Kareem.
