OAKLAND, Calif. -- It's a few minutes past 6 in the morning. The sun has yet to rise. But inside his dimly lit garage, Mark Shadinger, a man in his 40s with thinning brown hair down to the small of his back, lifts weights.
"Broncos today, baby, Broncos," he says between reps. "Man, I hate them. The best day of my life was when John Elway gave me the finger.
"Today we raise hell. Today we turn the Black Hole into an absolute jungle. No mercy today. It's the Broncos."
