The story of the week — a spawn of Michigan’s sign-stealing scandal — involves vague speculation of practice film hacking.

Alabama players on Wednesday said they stopped watching film on their personal iPads because of “what Michigan is known for,” running back Jase McClellan said.

Michigan coach Jim Harbaugh met with reporters Saturday for the first time since those comments were made at the Rose Bowl media day. He was asked about those comments from multiple Alabama players.

“I don’t know if somebody said that,” Harbaugh said Saturday morning in Pasadena, “but there’s been rumors out there about the cloud and the Catapult system. Our team is taking the same precautions.”

Harbaugh was then pressed on where he heard there could be a security breach.

“Rumor,” he said with a shrug. “People started talking about that. I know very little about how that works.”

Catapult, the company who hosts the cloud system that stores, responded to questions Friday from AL.com about allegations of security breaches.

“We are aware of the ongoing investigation of the alleged unauthorized access to NCAA football video footage,” A statement from a company spokesperson to AL.com reads. “We have conducted an internal investigation and have not found any security breach in our systems.”

Harbaugh on Saturday said he had no solid evidence of any practice film hacking.

“No, I think our university said we got hacked but I don’t think that had anything to do with it. Please know, I’m not accusing anybody of anything. I really don’t know.”

Alabama and Michigan will meet in the Rose Bowl semifinal at 4 p.m. CT Monday for a spot in the following week’s CFP national championship game.
