Lou Holtz says Michigan's alleged sign-stealing was 'illegal,' rips decision to suspend Jim Harbaugh midseason

Lou Holtz appears on OutKick's 'Hot Mic' to talk Michigan football's sign-stealing scandal.

Michigan football head coach Jim Harbaugh was not on the sideline Saturday as he began serving a three-game suspension. Last Friday, The Big Ten determined that the football program violated the league's sportsmanship policy.

Harbaugh and the university filed a complaint against the Big Ten and conference Commissioner Tony Petitti in state court Friday shortly after the suspension was announced. Michigan is seeking a temporary restraining order, which, if granted, would allow Harbaugh to return to the sidelines for the next two games.

Lou Holtz spent many decades on college football sidelines. Earlier this week, he appeared on Dan Dakich of OutKick's "Don't @ Me" show to weigh in on the ongoing scandal, calling Michigan's actions "illegal."

"I think it has to be investigated, but it is illegal what they did," Holtz said in reference to the sign-stealing allegations against Michigan.

Holtz added that he supports football teams doing whatever they can to gain an edge, as long as it falls within the rules.

"I'm all for getting an advantage during the game if you can do it legally, but this is really unfair to the other team."
