L.A. isn’t necessarily a land of bandwagoners. They are a land of transplants who grew up in other states and are fans of other teams prior to moving to Los Angeles.
It’s the reason why L.A. has failed so many times as an NFL location.
Also, the middle class people who are from the area and would support them as the home team have been priced out.
So the Cardinals should be well represented and there’s nothing Staffords pleas will do to change that.
