This I all I have to say on this matter.  You are correct sir, Hartzog was targeted the majority of the game and did extremely well.  On top of that the "Derp Man" himself @anon17440239 and many others in here are starting the narrative that our run defense game is the weak link.  While in this game is definitely was, and I think for the most part it was our scheme and how we defended.
If you look at Sorsby's passing stats from last year we shut down his arm, in turn opening up rushing lanes for him.  Every team we play we will have a different game plan, and one thing we do will look like it needs some work and some things we will look great in. 
We won the game and and also controlled the Time of Possession
Here is Sorsby's passing stats... I feel like we did just fine

A win is a win and even though the score was a 3 point win we still were the better team and played to our game plan.  I think Michigan is going to give us trouble, because they have a mobile quarterback.
