Brown is a very good coordinator. Sometimes the opposing team just has more talent on the field. Secondly, you can’t solely blame a DC for matchups that are exploited. Sometimes is just a great play or scheme from the offense that forced a bad matchup and took advantage of it.
Penn State played a heck of a football game and executed incredibly well. I thought Michigan’s defense would be the only thing that kept them in the game, when in reality it was the defense that failed them. They struggled to get any pressure, which left a very inexperienced secondary open to a feasting by good offensive talent.
