Looking at the 2014 version of Buckeye defense, it seems, from my couch perspective, that they are an improved unit from last year. They are not a unit capable of winning a game, by being shutdown/nasty. OSU's offense still has to be the superior unit, and out score teams to win, against above average/average teams. Looking at where the defense stands as OSU enters B1G play:
allowing 20 points per game, improved from the 22.6 points per game surrendered 2013
Gave up 370 yards rushing to Navy....... Rutgers held Navy to 171 yards rushing, but also gave Navy 230 yards passing
gave up 200 yards passing and 125 yards rushing plus 21 first downs to the most balanced offense they faced....Virginia Tech has climbed back to a 3-2 record, but they have yet to score more than 35 points this year, even in their other 2 victories against William & Marry or Western Michigan
Totally did what they had to do against Kent State
Gave up 352 yards passing and 4 TDs to a pass first offense Cincinnati
OSU has an improved defense, we can't call it piss poor, as was the case last season, but they still must get much better, if they hope to reach their goal of winning the Big 10 Championship.
