The NFL is once again posting stellar TV ratings but is having trouble filling seats in some markets. Jacksonville, St. Louis, Oakland and Arizona have all seen attendance dips this season. They've been joined by teams such as Pittsburgh and the New York Jets. The Steelers drew just over 60,000 fans to Heinz Field for last week's win over Buffalo. The Steelers host the Detroit Lions this Sunday. The Steelers are playing to 94 per cent capacity at home and could challenge the low point of 2004 when 91 per cent of the seats were filled.
