Big Ten coaches expressed frustration in a 90-minute call with commissioner Tony Petitti regarding the ongoing signal-stealing investigation at Michigan. The coaches, without Michigan’s Jim Harbaugh for part of the call, urged immediate action, describing the alleged scheme as “tainted” and “fraudulent.” The focus was on how Michigan’s illegal advantage impacted games. Despite acknowledging the NCAA’s timeline won’t affect the current season, coaches called on the Big Ten for action. Petitti listened but didn’t reveal a stance, leaving uncertainty about the conference’s response to the alleged violations.
