Depends on how the shared signs data was sourced. If, say, an Illinois low level staffer or fan, with Illinois having just played Michigan, sent a low level staffer of another team info about Michigan’s signs, that info almost certainly would have been sourced in-person. Stalions only had friends go watch games. If other teams effectively had personnel from other teams do the in-person scouting, that’s arguably worse. Maybe they didn’t use electronic means. Or less likely, maybe they didn’t do in-person scouting, maybe their equal at another school said “in advance of our game against Michigan, we pored over publicly available game tape and were able to figure out enough about Michigan’s signs, and we can save you the trouble of having to do so before you play them next week”
