Philly vs. Arizona-Good sign, bad sign or sign of danger?

[Defensewins]

When it was clear Steelers were going to win, CBS Sports game telecast showed an interesting graphic near the end of the Steelers v Chargers game.

Top three defenses in NFL in 2008 (ranking was based on total Defense):
1) Pittsburgh Steelers
2) Baltimore Ravens
3) Philadelphia Eagles

Then Joe Buck says, "how interesting the top three defenses in 2008 in total defense are represented as three of the finalists for the superbowl."

This was a CBS stat so dont ask me where they got their figures.

This is more relevant to who should win and how teams win then trying to make some kind of logic out of the first post in this thread about team beat A and team b...and trying to make some kind of logic out that. you can't.
