I Didn’t Know This,
but Kevin Holtsberry of Ideas, Etc., has a football blog named Pigskin. Kevin is a loyal Steelers fan (I am a maniacal Steelers fan- I stopped dating a girl when I found out her parents were Browns fans, and I cross the street if I see people wearing Cowboys paraphenalia so I don’t spit on them), so go check it out.
Also a must is Stillers.com.
