They can't score 100 points to save their life, but they can surely keep their opposition under 90 and if they can do that, they usually win. Now teams are not only contesting every shots, but contesting every possession. It seems pressure is put on every players the second he gets the ball near the three point line. 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.
