This is a concern. Here are his rushing numbers from game against Miami OH.
Rushing: M. Gray (MINN) - 25 CAR, 171 YDS
I think he will give us fits and it will look bad on National TV. Mark my words, this game will be no 2nd BYE week, it will be a close contest. I think Huskers still win but this will be the new Iowa State for Nebraska, a lose lose contest even if you win.
