Nick Van Exel seems intent on trying to stare down the NBA and its referees.  The Associated Press is reporting that, for the second time in a less than a week, Van Exel has been fined for calling refs who don't give his team the same breaks as others "cowards". Last time the hit was $10,000, this time it was $20,000.  Let's see, if he keeps this up until Christmas his fine will be $1,280,000 per incident.  Cancel that trip to Cancun Mrs. Exel.
