I agree. I watched the BWI post game on YouTube, and TFrank was saying Yurcich wants to run an outside zone where going back to Moorhead, PSU has run inside zone. The reads are different, etc. If thats the case, thats fine for the first couple of games in the season, not game 13. To me, it appears more basic. Penn State doesn't have a difference maker at RB, and the Oline appears to miss blocks on almost every play. Not knowing the right read is on the coaching. Missing blocks is partly execution, and partly coaching. As for not having a difference maker at RB, you can't coach athletic ability.
That said, Zack Zwinack ran for 1,000 yards in a season.
