It's one thing to prepare for it, watch film and walk through it against the scout team. It's another to maintain discipline when in the middle of a game against a better athlete at QB than any of these guys have played against before. Well, they played last year against Gardner from UMich, and that didn't go well either.
My guess is Ott/Meier do a better job in the future in the same situation. They might get their chance to see if they have learned this week if Colter plays for NU. And definitely in coming weeks against Gardner and Martinez.
What exactly would you expect Phil Parker to do? Other than magically get better players during the bye week? In the last 2 seasons, no B1G team has had an answer for Miller. Not one. Even the vaunted MSU defense gave up 136 yards rushing and 179 passing against Miller last year. And MSU had talent galore on defense that Iowa does not. Biggest difference this year for Miller is he's become much more accurate, going from 59% last year to nearly 70% as a passer this year. To defend this OSU offense adequately, you really need elite level talent at every level of the defense. No B1G teams have that and just a handful of teams in the country do. I'd like to see what Alabama's defense would do against OSU. Would be a good matchup.
Iowa needed to hope that Miller put the ball on the ground (he does fumble frequently). He did right at the end of the game (of course OSU recovered). I was surprised Iowa got 2 sacks on Miller. OSU has given up a whopping 10 all year. Side note: Iowa has given up only 5 sacks all year. That is a great number considering and testament to the o-line and Rudock's pocket presence.
But my point is it's not a matter of simply scheming to control Miller. If it was, someone would have come up with a plan and others would copy it. The sheer volume of athletes OSU throws out there on offense, paired with a very good o-line and a scheme that stresses the defense everywhere, makes them so difficult to stop.
