When I was a kid I thought that Pats logo the stupidest thing ever. And I didn't even dislike the Pats.
I think Packers or Steelers are solid choices.
But for OP's purposes maybe he should consider which teams are most likely to be shown in his area.
Being a fan of the Packers will be pointless if they never show the games over there because they're from a smaller market or something.
I agree that being a fan of the Steelers has merits because of the number of people EVERYWHERE that identify with that team.
I like Roethlesberger a lot because he went to my alma-mater.
But I grew up cheering for the Bengals and was pretty much programmed since childhood to hate the Steelers and find it difficult to change that.
If you are looking for personal info and/or feel-good stories to help sway your opinion here's an article about Roethlesberger dedicating the season to his late college coach.
