Great players are remembered. Pete wasn't one.
That's not true. He was a great player. Greatest of all-time? No, but lets not discount his importance and legacy to strengthen your argument for King, Kareem, etc. You don't need to do that.
Comparing King's and Maravich's shooting % is a little unfair, in that Maravich was taking lower % shots as a perimeter player vs King who was an inside player, and had the 3-point line existed, Pete would have averaged 50+/game.
Still, Maravich is everything you described him as; a gunner who lacked defense. His dad pushed him to be selfish because no one could stop him. He is one of the greatest passers of all-time, and was IMO, a victim of being way ahead of his time in that regard. Other players, at the time, weren't used to behind-the-back passes, no-look passes, and quick bounce-passes on the break.
Similar to King, Maravich faced some internal demons as well, and fortunately, had turned his life around before his untimely death.
