The NBA is mulling allowing ads on players' jerseys. Right now nine of the major sports leagues allow it, though it's obviously common in auto racing, golf, boxing, and soccer. Adam Silver, deputy commissioner of the NBA conceded "If we add sponsor logos to jerseys, we recognize that some of our fans will think we've lost our minds. But the NBA is a global business and logos on jerseys are well-established in other sports and commonplace outside the U.S."
