From a trusted source:
“I hate to say it because I do have great respect for Michigan and this rivalry, but I was talking to a colleague in the business that just played Michigan and his comment was, ‘Any play is a big play waiting to happen against their defense. They’re awful.’
“And that’s from a guy that in all the years I’ve known him has never really been much of a trash-talker. But he’s calling it like he sees it, and what everyone I’ve spoken to sees is a defense on the brink of total collapse, if it’s not there already.”
Recent second halves have left even opponents scratching their heads.
“What’s going on there? How can they look good for the first half and look like a MAC team in the second half?” a source asked us. “I just don’t get it. Do the coaches go into the locker room and rip the kids apart so they have no confidence? Do they try to change their scheme so much that they have them confused? What is it? I don’t get it.”
