A vast majority of the Big Ten coaches expressed their frustrations with the ongoing signal-stealing investigation at Michigan in a video call with commissioner Tony Petitti on Wednesday, sources told ESPN.
The call, which took 90 minutes, included nearly an hour without Michigan coach Jim Harbaugh, who hung up after the regularly scheduled Big Ten business to allow the conference's coaches to speak freely about the NCAA's investigation into Michigan.
According to five sources familiar with the call, a chorus of voices encouraged Petitti to take action against Michigan in a call that was described as both intense and emotional.
