Wow, someone agrees.
I was just get annoyed by how the announcers kept calling the Steelers the winningest and best franchise ever. If I recall correctly, even Goodell did, but I'm not sure about that, because there where all kinds of people talking on BBC.
Anyway, as for the modern era, I also agree with him. The Steelers have been amazing ever since the AFL and NFL merged.
As for the last decade, I have to go for the Patriots.
