Lets dive a little deeper, shall we?
Because of Minnesota's ball control offense and our defense not able to stop the run the possessions in this game were going to be very limited. Iowa had 3 real possessions in the first half and 5 in the second half for a total of 8.
Possession 1: the big pass to LaPorta put them in FG range, but a 2nd down sack on the bad snap really killed that drive.
Possession 2: TD
Possession 3: They had a couple of first downs, moved the ball from the 25 to MN 39, but then the bad snap over Petras' head took them out of being able to do anything on 4th down.
Possession 4: moved the ball to midfield from the 25 but missed on 3rd and 5 with throw to Lachey. Nobody's fault there, he was covered
Possession 5: Moved the ball from the 25 to MN 26, but then the corner blitz for a 10 yard loss that was much more on Ostrenga than Petras. Remember Ostrenga was playing due to LaPorta being out.
Possession 6: First 3 and out but this is the miss to Ragaini. It was there, Ragaini could have should have caught it. I don't blame Petras much because he had to put some zip on that throw because of the wind because if that throw hangs up its coming back the other way. It happens. Punt from our 41.
Possession 7: This is after the fumble and backed up at our own 9. 3 incompletions in a row resulted in a 3 and out. This was the most vulnerable possession of the game and one where the offense really needed to put 2-3 first downs together to flip the field like they had done all day.
Possession 8: After the interception, the big play to Lachey and the FG.
While you are correct that we only scored 13 points, the offense did its part in all except 1 of the 8 possessions to either score or flip the field. The reason why we won, aside from the turnovers, when Minnesota ran it down our throats is because they consistently had a really long field to go.
Do not lose sight of the fact that everyone we have played has a really, really good defense, especially MN, IL, WI, OSU, MI and ISU. All of those defenses are elite and especially if they can generate negative plays and get the other team into one-dimensional situations. I don't know what the stats are, but I would venture to say the percentage of drives that are killed after a negative play of any kind, let along a 10 yard sack, is very very high.
So to cap it off, of the 8 possessions that Iowa had, 3 ended in scores, 2 were killed with bad snaps, 1 killed with a missed protection on a blitz, 1 killed with a drop or missed connection on a definite explosive play, and the other was when we were backed inside our 10 yard line. This offense is not dynamic, few are, but if they can stay out of the negative plays and make the makeables, the scheme will continue to churn out wins. It is what it is all about.
