Criteria for the real Mt Rushmore wasn’t the 4 greatest - but 4 who had impact on the country - including at least in part, expansion.
George Washington - Bill Russell, father of modern basketball.
Thomas Jefferson - half-faced Larry Bird/ Magic Johnson, expanded NBA viewership.
Abraham Lincoln - Allen Iverson, changed the face and culture of the NBA.
Teddy Roosevelt - Steph Curry, his innovation has changed the way the game is played.
I do not think these are the NBAs 5 best players.
