CHICAGO — Jim Harbaugh gave it away.
When the Michigan coach - a guy who a year ago wouldn't produce a roster - begrudgingly said he would be "fine" with the institution of player injury reports during his press conference at Big Ten Media Days, it was a clear signal the league office and athletic directors have told coaches it's happening following the legalization of sports betting, and they have to get on board in order to try to insulate the sport from gambling-related scandals.
Harbaugh wasn't alone. No league coach did anything but support the idea at the two-day event.
