Purdue coach Ryan Walters was crystal clear when addressing the allegations circling the Michigan football program.

For the record, the NCAA is investigating the third-ranked Wolverines for violating rules regarding off-campus scouting of upcoming foes, with staff member Connor Stalions the alleged ringleader of a sign-stealing operation.

Michigan suspended Stalions with pay earlier this month, and head coach Jim Harbaugh denied knowledge of any wrongdoing.

“It’s unfortunate,” Walters said Thursday night on his radio show, two days ahead of the Boilermakers’ game against the Wolverines in Ann Arbor, Mich.

“What’s crazy is they weren’t allegations. It happened. There’s video evidence. There’s ticket purchases and sales that you can track back. We know for a fact that they were at a number of our games, so we’ve had to teach our guys a new language in terms of some signals and we will operate differently offensively … like you might see us in a huddle for the first time this season. So it is what it is, but we’re excited to go play, and I think it’ll make for a great story.”

Big Ten coaches expressed concerns with league commissioner Tony Petitti about Michigan’s alleged off-campus scouting on a conference call on Wednesday. Petitti is scheduled to meet with Michigan president Santa Ono on Friday morning.
