"Have any other former players or coaches actually come out to say they used game film to steal signals?"
Jimmy Johnson has publically admitted so in the past (http://www.bostonherald.com/blogs/sports/patriots/?p=2202&srvc=home&position=recent)
Q: Did you ever steal signals?
JJ: Oh in a heartbeat, yeah. Yes I did.
Q: Via video, Jimmy? Or no?
JJ: Oh yeah, I did it with video and so did a lot of other teams in the league. Just to make sure that you could study it and take your time, because you’re going to play the other team the second time around. But a lot of coaches did it, this was commonplace.
Q: But did you do it by taping the signal caller?
JJ: Yeah.
Q: Oh you did.
JJ: That’s what I’m saying. I was saying one of Marty Schottenheimer’s scouts, Mark Hatley, who has passed away now, Mark told me that’s how they did it, and Howard Mudd their offensive line coach with Kansas City, who now coaches for Tony Dungy, he was the best in the entire league at stealing signals.
