Go to any gym across the country and take a jump shot. Pretty easy right?
Go do the same thing in a pick-up game with a guy defending you, closing you out. Not so easy, right?
The name of the game in basketball is to work together to get easy shots. That is why part of the revolution in the NBA has been to find the best ways to get these shots. The rise of the corner 3-pointer is both a recognition of the fact that it is the closest 3-point shot on the court and the fact that it is easy for penetrating guards to kick out to the corner.
