It's based on data

Where do people come up with this stuff?

Fans are emotional and lack perspective. Analytics don't do that. They
don't play favorites. They do the numbers and they fall where they may.

No agendas, no emotion. Significantly detached to have good perspective.
They do all the teams and can do comparisons with their data.

Unpopularity, popularity, neither one figures into it. And that's not the only
site. Football Outsiders has similar rankings.
