Will moving the line help?

I am doubtful that moving back the 3-point line will help much in bringing about better shooting. The players are accustomed to blasting away from there, and a little lower shooting percentage is not going to deter them much. If there is any shooting discipline as a result of moving the line, it will have to be because coaches enforce it. Besides, shooters could do pretty well even from halfcourt if they shot from there all the time, such as is the case with the 3-point line. Muscle memory can be an amazing thing.
