Obv I have a major bias when it comes to this.
This guy has been around the program for years, even people like Devin Gardner remember him being at almost every game. Add in the Navy grad and veteran stuff and he had credibility. He comes to the school saying he figured out signs from TV (varieties in the SI article) the school believes him due to the credibility and sees that he’s right. Again we don’t know how much of his info they used or even how effective it was.
People seem to be jumping to a conclusion due to the record the past couple years that it was incredibly valuable but understandably don’t realize that these teams the last couple years have been the most talented Michigan teams in decades, especially when the rest of the league has been down.
So if it has some value they add the guy to the staff and pay him basically nothing believing that he is getting the info from TV/film (which is legal) like he stated. Again I have my bias but I just don’t think Harbaugh would cheat on the field. Buy a couple burgers sure, have extra practices or recruiting talks, yeah, but I just can’t see him cheating on the field. I could be completely wrong but that’s just where I’m staying until I see a single fact that said he or the coordinators knew.
