Only times I’ve ever heard it happen was Sumlin’s last year at A&M and Orgeron at USC when he was interim trying to make sure he didn’t get the full time job. Both just rumors.
Sort of along those lines.. apparently someone was paid off when Tennessee and Virginia Tech played at Bristol Motor Speedway to reroute Virginia Tech’s radios to their signal or tap their radio and relay the communication and sure enough.. they got down 14-0 pretty quickly and then immediately turned it around and destroyed them. I don’t know if it was a Virginia Tech staffer leaking it or gave them the “how to” or if it was just a random spy.
We (ETSU) played west Carolina there after that game and they had to close off the suites that weren’t booked for that one and had security in there because they had found a piece of equipment left in an “unoccupied” suite and some notes in the trash clearly charting play calls and trying to decipher what the calls meant.
