because theres a foul, at least by the spurs, every possession,the tactic seems to be to dare the refs to call every foul. just since you posted I watched three clear fouls go uncalled. its not just the bumping and grinding of playoff basket ball either, its hacking outside on the drive to the basket, clear body contact by the defender is supposed to be called a foul.. this negates the speed advantage the clippers have . they are rattled now.
