Who is the Best scorer in NBA history?

those 4 are definitely the greatest scorers of all-time. As for who is the best I really don't think there is a right or wrong answer, but rather more of an opinion. Although I think its MJ. He is 3rd on the all-time scoring list and he only played 15 seasons, 2 of them were with the wizards at 39, and 40. Kareem played 20 seasons.
