"A good offense that has really studied film and really done its due diligence will see plays that other teams have had success with and install them as a surprise," Sherman says. "Brandon Browner got beat in Arizona on posts from two outside receivers, and flats from the slot receivers. And they were the only team that ran it. Kam was the safety and he tried to undercut the post and they just banged it in there. Denver had never run it, and they put it in because of Arizona. That's chess."
