What's an NFL franchise that you sometimes forget about?

For me, it's the New York Jets. I don't know why, but for some reason they are always the last team I think about when talking the NFL with people. Maybe it's because in my 33 years of life, I can't remember them ever being relevant.

Edit: I am 33 years old and grew up watching football but I lived in Michigan and followed the Lions. I didn't watch much football when I got to college so I missed the time when the Jets were relevant and I recently started watching again a few years ago so in my memory, the Jets have been an irrelevant team.
