A decent DC.
BGSU's possessions looked like this: Punt, TD, Punt, FG, TD, EOH, TD, TD, Pick-6, Punt, Downs, EOG.
They scored 31 points on 5 of 6 possessions from possession #2 through #7, not counting the EOH. Then they capped that off with a Pick-6.
It was 17-14 at the half, and by the end of the 3rd it was all done, 38-20. It was that fast. It totally negated our running game.
Our D never stopped them on drives that began in the 2nd and 3rd quarters. Not once. They scored on every possession that began in those two quarters, except the EOH.
Even with the O pulling its Jekyll and Hyde stunt, w/o that, we would have won.
Just one stop in that timeframe may have done it. Say, for instance, we stop them coming out of the half. It's still 17-14. We then kick the FG on our first possession (at the 14) to tie. Then they score to go up 24-17 in the late 3rd. It's a 1-score game. We're not desperately throwing the ball and likely avoid the pick-6. The game very well might play out totally different.
Just one stop.
Now the O could have done it, too, but it would have required we score on every 2nd half possession and not rush into that pick-6. Then it's 24-14, then 31-21, then 31-28, and then finally 34-31.
That's much harder to do than simply getting a stop or two by the D.
