Big Ten athletic directors met with commissioner Tony Petitti on a video call Thursday without Michigan athletic director Warde Manuel present, and sources told ESPN the call about Michigan's alleged sign-stealing operation took on a distinctly different tenor than when they met a week ago.
Sources said the athletic directors left the call with the notion than Petitti is taking the Big Ten's ability to punish Michigan over the allegations more seriously than before.
While no potential punishments were discussed, Petitti acknowledged speaking with the NCAA about its investigation, although he refused to divulge any details of that conversation, sources said.
One of the issues Petitti brought up with the athletic directors was that he couldn't make a decision on Michigan this season based on a whim, that he would need a set of facts to go off of.
