The NBA has become a perimeter game. This has been an on going trend in the NBA. Everyone wants small quick players who can drive to the basket and shoot threes. The evolution of the power forward position makes many of them perimeter players as well. No longer are power forwards backing down their defenders or rolling to the basket on a pick in roll. Many of them are shooting mid-range jumpers and popping out for a shot. People don't understand how important post-play is in basketball. Post play is similar to an isolation game except you start closer to the basket. What team wouldn't want their best player with the ball on the block near the basket. Plus it is much much easier to pass the ball out of a double in the post since you can see your teammates better. As Glen Davis has proven you dont have to be the tallest or even strongest to get it done in the post. All it takes is a few solid moves, a spin, a hook shot maybe a nice little fade away. These are not hard things to learn it's a matter of practicing them and getting down the footwork which NBA players should be sufficient at. The best defensive teams in the NBA can stop quick drives to the basket with good help defense and a quick rotation. Their is no defense for a good post move! Their is a certain unpredictability that goes along with it. The teams who can play down in the posts are better than those who can't and people don't realize that. It is why the Lakers have won the last two NBA titles.
