There is only 1 basketball in play during a basketball game. If a team has more white players on the court than there are basketballs in play that team has a greater chance of loosing the game. The ratio should be at most 1 to 1 and ideally 0 to 1 (no white guys to one basketball). This is not a 100% guarantee just a good rule of thumb.
Most pro & college basketball teams have very few white guys and infrequently play more than 1 at a time. They almost never violate the white guy to basketball ratio rule.
