Leroy Butler has several good lines in his last answer including a dig at the AFC and my favorite, highlighted below.http://www.jsonline.com/story/index.aspx?id=808008
Q: How much could Favre really tell the Lions? Do teams change their signals from year to year? Would he be able to share things about Mike McCarthy's play-calling? Would he be able to give them all the audibles?
A: The West Coast offense is all the same. You put in wrinkles each week. If he wanted to go, 'Well, when you have a single safety down in an eight-man front, Aaron will throw slant routes' or "if Driver is 2 yards from the sideline it's a go route', it's possible he could do that. Coaches do that. They call up each other and say, 'What did you do to beat them?' But Detroit has all these scouts and coaches looking at film, they can pick up more stuff than Brett can give them. I guess he can give them ideas like 'Against teams who play a lot of Cover-2, these are the plays we like to run.' That can be very effective. Or 'If they think you're in man-to-man, these are the plays they like to run. When I was there and we had five wide receivers on the field these were the first three or four plays out of Mike's mouth. He'll stay true to it, so tell your defensive backs to play inside more and they'll have a chance at an interception.' So, things like that could happen. The audibles can be changed year to year. The thing Brett would never know are the signals Aaron Rodgers has with his wide receivers. They change that all the time. Only they know what it is. That's something Rodgers comes up with in the meeting room with the receivers. As for whether it's out of bounds, I don't think so. He's in the AFC. They're always doing that kind of stuff. They don't that in the NFC much. This is America, you can do what you want
. I don't know any code that you can't talk to guys. You do what you want. But to tell you the truth, a lot of that stuff won't help. As a coach, are you telling me the only thing you can come up with to defend me is what Brett said? C'mon, tell me you have more than that.
