Bigsby rushed for 4.4ypc against PSU (with an OL that mostly returned from last year)
For comparison, in his freshman year last year Bigsby's YPC stats were:
vs UK: 2.5
vs UGA: 3.9
vs ARK: 7.3
vs SC: 6.9
vs MISS: 5.4
vs LSU: 4.7
vs TENN: 8.0
vs ALA: 3.5
vs A&M: 8.4
vs MSU: 7.4
While I would like to see PSU do better in stopping the run, only Alabama, UGA, and UK did better against him last year on a YPC basis. Auburn has a really physical running game dating back to last season, and I was impressed how well PSU matched the physicality.
Improvements can be made, but I am feeling pretty freaking good about this PSU defense right now through 3 games. I don't see most of the other teams on PSU's schedule matching the physicality of Auburn in the running game (including OSU). Michigan poses a worry for me in this regard. I don't think Iowa can bring the physicality the way Auburn could.
