MIAMI (AP) - Commissioner David Stern says the NBA's flopping penalties aren't strong enough to stop the act, though he doesn't know if the league will strengthen them.

The league implemented a system this season to crack down on flopping, the act of exaggerating contact to fool referees into calling a foul. Players were fined $5,000 for a second offense during the regular season, and were hit with the $5,000 penalty for a first instance in the playoffs.

Stern says Thursday that's not enough in a league where the average salary is $5.5 million. He says suspensions "might be a little bit draconian at the moment," and that he doesn't know if the league will "have the stomach" to strengthen the penalties enough to really get the act stopped.

He adds that owners and the Competition Committee will have further discussions.
