I was not worried about either line's play yesterday. The OL was markedly improved in both run and pass blocking. From what I recall, at least three of the four sacks were Braxton's fault for holding onto the ball way too long. Contrast that with last year, when pressure came the moment after the hiked the ball. When he fires the ball out of there quickly, like he's supposed to, the line will look better. There were also at least four or five times he should have been sacked but the line held up longer than it would against, say, Michigan State. They were far from perfect, to be sure, but clearly better than last season.
I find it funny that people are panicking about the DL. Miami styled its entire gameplan to neutralize Ohio State's DL. They passed 54 times and ran it 20. Those 20 rushing attempts netted -1 rushing yard. Yes, of course sometimes Dysert had time; you can't get pressure on every play. But with Miami going four and five wide for 90% of the game, keeping a fourth down lineman would have opened up a bevy of big passing plays, some of which Miami connected on in that first quarter. Rushing three and dropping eight works out well for limiting the big play downfield, not so much for pass rush statistics. Only Bollman-coached lines consistently give up sacks to three down linemen. Any competently coached line can handle it, especially with an experienced, NFL-bound senior throwing behind it.
The defensive line actually got more pressure than I expected against this offense, but Dysert was good enough to turn some of those pressure plays into first downs. How many QBs with as much starting experience as Dysert will Ohio State play this year? I'm not worried.
