This is a weird topic. I didn’t even know teams couldn’t watch future opponents in person because of a 1994 rule that was put into place for monetary reasons. Secondly, to believe other teams haven’t done this is foolish. There’s a reason teams like Oregon started using odd pictures to call plays. Lastly, it’s even weirder to claim Michigan is only winning because Harbaugh is cheating. It’s a huge disservice to some of their talent that has filled the rosters the last couple years and currently.
All that being said, it’s a shame if they are breaking a rule.. although one that is likely extremely outdated. What’s sad is that college football has been on a terrible path the last 10 years and will no longer look like what I grew up with.
