Per Fanation, your assessment would be correct. Coach Frost said all workouts were approved by administration. Now I don't think he addressed the analyst issue in that statement
School making the allegations provided the footage. So which b1g school turned us in? That rules out Wisconsin. Someone we beat? Penn State, Rutgers or Purdue? Minnesota Iowa, nw, ill or tosu.
Wouldn't surprise me if it isn't Ill. New coach watching film close looking at personel and coaches trying to figure out who's who, what they're doing etc.
I also assume it would have been a school that was an away game since they would have more readily available film in their possession.
