NFL Fan Bases: Ranking NFL Fan Bases by Attendance

15. San Francisco 49ers (Average Attendance: 68,924)

The San Francisco 49ers were at the height of the football world just a few years ago under the leadership of Jim Harbaugh. Since the departure of Harbaugh, the 49ers have struggled to find success, although they do seem to be trending in the right direction under new coach Kyle Shanahan.

While the 49ers have been rebuilding, their fan base continues to show up to games as nearly 70,000 fans have come to each of their home games this year. In fact, their stadium is listed to be at full capacity with the amount of fans that they draw each week.
