I think like what every one else has been saying is that the 3 point line helps open the floor. The problem is every one shoots it because of when they pulled it in years back, all the bigs decided they could shoot 3's too. In 5 to 10 years you'll see that start to disappear, hopefully, I like my bigs to be 15 feet and in at most times.
The other problem is you can't drive to the lane anymore because of the offensive charge rule. It use to be no line and if the player was out of controle, and the defensive player was set. No the offensive player only had ONE step to change direction or stop. At full speed no way that can happen, and it time an actualy NBA player takes over as comissioner to change some of these rules, cause Stern really dosen't know much of what it take to play the game, he's really ruined that, but thats for an other thread!
So if you can't drive to the hoop what are you going to do? Shoot the three ball because you don't want to foul out.
