Too often it appears that I see refs officiate dependent on a team's defensive style, particularly in conference play. If a team is known as a pressing m2m 'in your face' defensive team they appear to allow them more contact than a less aggressive pick 'em up after half court m2m style or a zone defense. They either consciously or subconsciously accept a team's physicality as acceptable if it's a signature of their defense. You can't depend the way games are called that there's a defense that better protects players from fouling.If you look at most box scores, regardless of the competing team's defense, officials seem to keep the number of fouls called pretty even regardless of a team's physical defensive style. When they call them - whether on shots vs away from the basket fouls etc, affecting the number of free throws can differ but the number of fouls are usually pretty equal. It sometimes seems to catch up with certain teams in tournament play and away from conference officials.
