It's interesting concept when you think about it because OSU's defense has almost every stat in their favor, showing they're among the best, but OSU offense rarely put their defense in tough positions or rarely gave the defense a break. Only time I remember seeing it was against Michigan because OSU play calling took peed on their own leg that day.
This is a very fair point. As usual, I like the College Football Nerds solution of ranking by yards per carry and yards per pass attempt because that MOSTLY takes out the impact of the offense being good or bad.
I also like that they do it relative to opposition so if you play a bunch of teams that suck at passing you don't get an unrealistically good ranking based on their inability to throw. Instead, you are compared to how they did against their other opponents.
Passing yards per attempt allowed (relative to opposition):
- #1 Fresno State, 5.78, -27%
- #2 Texas, 5.61, -27%
- #3 Notre Dame, 5.67, -26%
- #4 Ohio State, 5.62, -24%
- #11 Michigan, 6.46, -18%
Rushing yards per carry allowed (relative to opposition):
- #1 Ohio State, 2.42, -44%
- #2 Ole Miss, 2.28, -42%
- #3 Michigan, 2.87, -31%
Michigan does MUCH better on these per-play metrics than they do on the per-game metrics where they were #27 in passing defense and #4 in rushing defense.
Total Defense:
- Ohio State was #1 overall and #1 relative to opposition at 251.07, -33%
- Michigan was #10 overall and #8 relative at 307, -20%
Scoring Defense:
- Ohio State was #1 overall and #1 relative to opposition at 12.20, -57%
- Michigan was #17 overall and #11 relative at 19.92, -30%
There is no doubt in my mind that Michigan's defense was at least solidly in the top-10. In those areas where they rank outside of that I think that their offense incompetence made their defense look bad*.
Another factor that it is REALLY hard to eliminate is the fatigue factor. If your offense sucks and can't move the chains then your defense gets forced to play a whole lot of plays and tends to wear down over the course of a game. This was DEFINITELY an issue for the tOSU defense on Michigan's final drives in The Game. Their final two drives were:
- 15 plays, 77 yards to the shadow of the goalpost then an INT
- 11 plays, 57 yards to the game winning FG.
Michigan only gained 234 yards total so it is telling that they got 134 of those yards or nearly 60% on their last two possessions.
That impacted Ohio State in that game but it impacted Michigan pretty much all year long.
*Offensive incompetence making defense look worse than they actually are:
Once again the same thing happened to Ohio State in The Game. Michigan got their TD on a possession that started at the Ohio State 2 yard line and they got one of their FG's on a three-and-out that gained 3 yards. Vis-a-vis who won that makes no difference but if you are trying to evaluate the offenses and the defenses as separate units then you should give the credit/blame for those two scores to Michigan's defense and Ohio State's offense.
Similarly, this impacted Ohio State in that game but it impacted Michigan pretty much all year long.
