Allison has fumbled three times this year. He's the only running back on the team that has fumbled at all (none for Ross or Tuggle in their Ohio careers). He's clearly gotten a second and third chance, and I'm sure he'll get another, but so far, he's not gotten the message. He was in the open field and lost the ball from a hit by a defender he knew was coming. Rourke lost a fumble because he got blasted when the offensive line didn't block. It's a big difference. That's on the offensive line. Allison's fumble is on him. It was pretty big too, one of the key reasons Ohio lost. Hopefully from now on, he'll make it a point to hold onto the ball because he probably is the team's best overall running back.
Agree completely with this. He's a hard runner and could be an AJ-like back given another year in the weight room. However, you could feel it in the stadium as soon as it happened that it was going to come back and bite us. It shouldn't be too hard to teach an FBS running back that, when you're fighting for extra yards, you HAVE to protect the football. I'm guessing that is a huge part of Solich's frustration with him.
On the Rourke fumble, I couldn't see who's man got to him, but if it was a blind side hit, then that's a recurring problem with the left side of the OL.
