Sources - Big Ten coaches urge action vs. Michigan in call - ESPN

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.

«Collectively, the coaches want the Big Ten to act — right now,» said a source familiar with the call. «What are we waiting on? We know what happened.»

The NCAA has been investigating Michigan for nearly two weeks, as the Big Ten confirmed the NCAA's sign-stealing investigation on Oct. 19. Since that time, ESPN has reported that Michigan staffer Connor Stalions emerged as a centerpiece of the investigation and has purchased tickets to the games of 12 of 13 Big Ten opponents over the last three years.

Overall, Stalions has purchased tickets to more than 35 games in at least 17 stadiums over the last three years, ESPN reported. Michigan suspended Stalions the same day ESPN reported he was the center of the investigation. A former Division III coach also told ESPN he was paid by Stalions to video games at multiple Big Ten schools.

The coaches in the Big Ten laid out to Petitti, who was hired in April, just how distinct of a schematic advantage Michigan has held the last three years by illegally obtaining the opposition's signals ahead of time, as has been alleged.
