NBA vice president of basketball operations Stu Jackson confirmed Wednesday that several new rule interpretations will be a point of emphasis for the league's referees when the regular season begins on Dec. 25.

"Rip-through" moves, in which an offensive player swings the ball into a defender's outstretched arm and then attempts a shot once he has created contact, will be considered non-shooting fouls if the contact begins before the offensive player starts his shooting motion.

Also, on drives to the basket, a shooting foul will be called only if contact occurs after the offensive player has begun his shooting motion, not after he has initiated his leap toward the basket.

Whether a player's foot is on the three-point line or midcourt line will be determined by where it last touched the floor, meaning a player could have a toe on the three-point line but if he leans back on his heels before he releases the ball a successful shot would be deemed a three-pointer.

Referees also will be hyper-vigilant about defenders making contact with offensive players when they're in the air and fully extended attempting to score. In most cases, expect that kind of foul to draw a Flagrant Level 2, which is two free throws, possession of the ball and the defender being ejected.

The last rule is necessary because the 24-second shot clock will now be equipped to show 10ths for the final five seconds and work as a "true" clock. From a technical standpoint, the old shot clock began with 24.9 seconds and expired with .9 left. Now the clock will switch from 24 to 23 seconds after .1 second has expired.
