Back in the Dark Ages when I played, the best way to open up the inside was to actually hit shots from outside and make them come out to guard you. It is difficult for me to see how longer and more unsuccessful shots will do anything to loosen up or clean up inside play. Leave the line where it is and start calling fouls inside for holding and smashing into the opposing player. In the long run, college basketball will be better for it.
NCAA may move 3-point line
