I've always been taught the way CK mentions: outside position from the lane line out to about the 3-point arc, and inside position from about the arc to the sideline. It seems to work better for me because if I am outside the player, as I back away slightly I can keep that player and the lane (my primary) within my field of vision. If I'm inside, it's hard to keep the lane and the player within sight at the same time, especially if I don't have a lot of room to back up. I would hate to miss a throw-in violation just because I was too intent on watching the paint. Or visa versa.
