INDIANAPOLIS — It was a slight cosmetic change, the kind of subtle modification most people would fail to notice.
Just as he did last year at Big Ten media days, Jim Harbaugh wore a navy suit as he made the rounds Tuesday at Lucas Oil Stadium. But his yellow tie wasn’t the same. Harbaugh ditched the straight diagonal stripes and went with a pattern of oddly-shaped X’s and O’s that was louder, less congruent and more distracting. The piece of cloth hanging around his neck, in many ways, captured the essence of Harbaugh’s offseason with Michigan football and how different it was than his last.
