Just in relation to what I was saying about in person scouting being illegal because of costs not actual sign stealing.
When you see the allegation of "vast network" you wonder if it might have been fans or boosters at games sending video to Stalions or Michigan staff who then would decipher it themselves.
Here's the excerpt from an Athletic article:
The relevant NCAA rule is bylaw 11.6.1, which prohibits “off-campus, in-person scouting of future opponents (in the same season).” The rule was passed in 1994 as a cost-cutting measure designed to promote equity for programs that couldn’t afford to send scouts to other games.
The bylaw also prohibits an institution from “employing or paying the expenses of someone else, including professional scouting services, to scout the opponent,” according to the NCAA’s legislative database.
One source who was briefed on the allegation said Michigan is accused of using a “vast network” to steal opposing teams’ signs. If true, that would be a potential violation of the NCAA rule against in-person scouting and would be adjudicated through the NCAA infractions process.
The NCAA’s 2023 football rule book prohibits “any attempt to record, either through audio or video means, any signals given by an opposing player, coach or other team personnel.” Using an electronic device to record signals would fall under the category of prohibited field equipment.
