You're right. It's not more absurd (and narcissistic) to think that "you" (some dude on a message board) could win a SB because they were give a superb defense.
You're obviously awesome and Brian Billick, who put together one of the most dynamic offenses in NFL history and then won a SB with virtually no offense and is still employed in the sport at the highest level, is a complete rube.
I love the internet.
