23. Pittsburgh SteelersĀ (Average Attendance: 63,082)
Everyone get out your terrible towels, we are talking about the mighty Pittsburgh Steelers. The Steelers are regarded as one of the class organizations in the NFL, with one of the strongest fan bases.
Yet they find themselves near the bottom of this list of attendance.
For the Steelers it is not even due to limits in their stadium, as they are only at 92% capacity filled per game on the season. As much as Steelers want to puff their chests as the best fan base in the NFL, they are not supporting their team to the fullest this year.
