Truth About Videotaping in the NFL

its not even about just the signals


its about knowing "on 3rd & 6, when ___________(insert team) lines up in the I formation wit 3 wrs, they usually run ________________, but when they r in the redzone they use that formation but they do this ___________"

& the same goes for defensive packages & plays, zones, blitzes all of that

little sh*t like that, its having more then reasonable knowledge of tendancies...
