This is how the first play of the season read in the Box Score - Play by Play recap:
1st &10 at MICH 27
Shea didn't slide, got hit in the ribs, fumbled the football and after a few more plays, Michigan is down 0-7 to Middle Tennessee State.
There is plenty to be concerned with the above statement including, Shea hurting himself which will have plenty of negative effects through 4 games. It started with over throwing open WR's. But the biggest negative effect has been, limited to no QB runs.
If you ask a DC, most will admit that preparing for an athletic QB that can run is nearly impossible.
