PEYTON and ELI MANNING are in a new ad for DirecTV. It's a fake promo spot for a TV drama called "Football Cops" . . . and instead of using guns, they kill criminals with deadly footballs. It's not clear if there's more to come, but DirecTV is promoting it like there is. Odds are, DirecTV is just planning to run mini-episodes leading up to the football season . . . if there is one.
