As I was cruising the net, I came across a 247 article about the last time each Big Ten team lost to a non-power 5 school. I was quite surprised about some of the losses and that was the Appalachian State win over Michigan in 2007 was not their most recent loss. I used to laugh when I saw the empty Stadium for the Miami Hurricanes. I will not laugh any more.
