Why not have only one foul line for pointing and hitting?
The pointing foul line is 6 feet from the backboard; enough space to allow sufficient room for a one step delivery, yet not use up too much of the playing area. The hitting foul line is further out since most players like to have a running start (much like bowling) to implement a hard throw. Having a pointing foul line closer to the backboard creates a larger playing area for shorter courts.
