Under the basket throw in position.....

[jdw3018]

Moving the player out away from the lane puts them at an advantage or disadvantage that is not intended.

Many teams have very precise plays they run depending on where the throw-in spot is. This different spot could give an advantage, or be a disadvantage, to a team that has a specific play to be run from the end line under their own basket.

Getting throw-in spots correct is a pet peeve of mine. Even in the backcourt I want to give the ball at as close a spot as possible to where it should be. Nothing irks me about a partner more (well, maybe other than one who has no interest in giving decent effort) than refusing to put the ball in play where it should be...
