Every ball loose ball is dived for. This is great for the game, but scoring is suffering. Defense is preached so much as of late, that teams neglect the offense. It's kind of sad. I watch Utah and they use surgical like precision when running their offense.
Most teams use a basic set.
Throw the ball in the post, wait for the double team and swing it to the open player. The problem is that players aren't able to make that shot this year. Add to that the short training camp and players haven't gelled the way they should have, new coaches, new players. Look at Utah. They are running at nearly full speed.
