Ohio State was bunched out, three receivers on the right, two offset with the third, Luke Farrell, up on the line of scrimmage. Because K.J. Hill and Chris Olave were the two offset, Michigan did the sensible thing and assumed a screen was coming. It didn’t. Ohio State was running mesh, a favorite of the Ryan Day (and air raid) offense, and Michigan was in man-coverage. You don’t want to be in man-coverage against mesh (though there’s really not a great solution for mesh), and Ohio State is going to show Michigan why in about a half a second.
