I voted for all of them (with the Cowboys being the most hated team for me), except the America's Team question. If there is a "None of them" option, I would've voted for it.
Why? Well, because the Green Bay Packers are known just as the Green Bay Packers. They won titles, played hard football, and developed a winning tradition simply under the title of the Packers. Lambeau, Hutson, Lombardi, Starr, and Favre played for the Packers, not "America's Team". They can be referred to as "America's Team" by the fans and the fact that the Packers are publicly owned, but the Packers can easily make it an official title. But they didn't.
The reason is because they don't need to. The Packers already has an illustrious history, an extremely loyal fanbase, a winning tradition, and 13 world championships. They made an identity with themselves with these accomplishments. These traits attracted not only fans of football in America, but the entire world, so the title "America's Team" would not even begin to cover the reaches of Packer Nation.
Plus, I think the title's a bit pretentious.
