You also need to look where both teams were ranked at before the season started. Duke and Gonzaga both were top 5, and Duke lost by 2 on a neutral court. Michigan was way down, if I’m not mistaken.They are pretty comparable. Like @jhmossy said, if you swapped their wins and losses undefeated Duke would be ahead of 1 loss Michigan.
Yeah, Duke gets a lot of attention, but if both Duke and Michigan were to lose the same day, see who gets more coverage on sports center.
