The NBA will have a bit of a different look to it this season, especially when it comes to defense.

In an effort to create more team play and, eventually, create more scoring, the league instituted key rule changes that allow for more team defense.

The biggest changes fans may notice:

* Illegal defense guidelines will be eliminated.

* A defensive three-second rule will prohibit a defender from remaining in the lane without closely guarding an offensive player.

* A team has to get the ball past midcourt in eight seconds instead of 10.
