While the small capacity at State Farm Stadium certainly puts them at a disadvantage, the Arizona Cardinals wrapped up their ugly 2022–2023 season ranked 28th in attendance.
With an average of 65 thousand fans per home game, the Cardinals finished ahead of just the Lions, Raiders, Bears, and Commanders.
Not to mention, as anyone who has attended a Cardinals home game can attest, the opposing team has always had no problem filling the seats with their fans in Arizona.
