If this helps you, from the Athletic:
Georgia coach Kirby Smart said Tuesday that while sign-stealing during games is nothing new, he had never heard about what
Michigan is accused of doing: advanced scouting of future opponents to deduce their signals.
“I had never heard of anybody going to the games to watch and film and do all that stuff that that’s going on that people are talking about,” Smart said. “I don’t know anybody that’s ever done it. Or I’ve never been asked to do that as a young coach or known anybody to do that. I’ve never even heard of that.”
...
“No I didn’t notice anything or know anything; nobody we talked to warned us or anything like that,” Smart said. “I think everybody we play they say, ‘They steal your signals.’ We play somebody, and they say, ‘They’re great at stealing your signals.’ But what they’re referencing (at Michigan) is different than stealing them. They’re talking about people to come and film on us. But we’ve tried to hide the signals, hold the calls, put signs up, do all that. But there’s nothing I remember about the Michigan game that makes me think that.”

How much does Georgia do it? Not much, to hear Smart and one of his players tell it. Smart didn’t deny that it happens but indicated it wasn’t helpful, especially when he was trying to call a defense.
“As a signal-caller, when I had to call defenses, it confused me if I had to sit there and wait on somebody to tell me what they thought they got,” Smart said. “I’m trying to think about what the best call for the situation is, and you’re relying on misinformation or something that’s not very reliable.”
Georgia linebacker
Jamon Dumas-Johnson was asked how much it would matter to know the offense’s signs.
“It would be huge. But I don’t think we sign steal over here,” Dumas-Johnson said. “Our preparation, our coaches doing their job, I think that’s why we’re very successful defensively the last few years. I think that goes to our preparation, the coaches doing their job. I don’t know about any sign stealing.”
