Michigan's football team impressed me as a complete and very cohesive team this week. I don't much pay attention to the Big 10, but Saturday's Penn St. vs. Michigan was the most compelling early matchup and so I watched it - slightly rooting for Penn St. Michigan's offensive line pushed around what I thought was a pretty strong defense going into the game, and Michigan's defense played as a unit, the best I've seen any team play in an important game recently. Their positioning and tackling was more precise than I'm used to seeing in modern football.
