They're valuable but you have to fully understand why they're happening. The other team's defense is dying because of our elite our defense is. Ohio State has played better offenses than we have.So let me get this straight... you're actually arguing that Penn State's rushing yards are mostly in the 2nd half of games (and, therefore, not as valuable?), but OSU's rushing yards are evenly dispersed for each half and even each quarter? And only PSU opponents get tired in the 2nd half, but Ohio State's opponents are equally strong in each half? That is laughable, but even if it were true - it doesn't matter when we get the rushing yards as long as we get them. In fact, I'd rather be able to run the ball, grind out 1st downs and score points in the 2nd half than in the 1st half.
Regardless, in those same 4 non-FCS games, PSU averaged 3.87 yards/rush while Ohio St averaged 3.96 yards/rush. And if you just take away the one long 61-yard run by OSU vs Notre Dame, Ohio St's overall rushing yards and yards/rush average both decline significantly.
So--Ohio State and Penn State are basically the same in yards per attempt (which you should have known before the crazy rant) to the point you're trying to eliminate a long wrong because we lack explosive plays.
