Lots of teams are going to odd front defenses. They are a ***** to block and you put another athlete on the field.

I saw WI hold Iowa once to like 60 yards TO with a 3 man front.

ISU hasn't made basic plays in that game and that's been a bigger deal than the defensive alignment.
Yeah, the special teams and offense in September games have been hot garbage in the Campbell era. There's no way to sugar coat it. He's 1-5 in Big 12 openers. 0-6 against Iowa. Hammered by Louisiana. Two of the wins ISU was lucky to escape against UNI.

Campbell has been masterful at pretty much everything, but developing the OL and being ready to play in September games have been problems that I'm betting he'll figure out.

Of all the things to worry about as an ISU FB fan, the 3-3-5 is about last on the list.

Do we not include kicker as a part of special teams? Mevis was great last year. Like, good enough to have our overall special teams be close to average.

JFC, the defense has done their job against Iowa but way to pick an extreme outlier....

Point being it's not the alignment that's the problem.

The secondary was still leaky and the other two areas of the game have been bad.

It's just incredibly frustrating when the staff can find and get undervalued guys at every other position. Well, maybe CB not so much. They can evaluate and project so well that they don't have to battle the blue bloods very often to get good B12 players and even all-conference players. OL has not been that...I don't know if scouting is easier there or what. But we're getting (for the most part) iowa's leftovers, Minnesota's leftovers, Mizzou's leftovers, Wisconsin's leftovers. Yes, there are exceptions like Hasert and Downing, but mostly, our OLs are living up to their recruiting rankings, which isn't great. Other positions, they perform above their rankings. Something needs to change there for us to take the next step.

I think that may be changing... we will see.

In 2016, we got Brian Bobek (transfer from Minn, OSU for one year) and Sean Foster, who at least saw the field...

In 2017, again, over half the class had little or no action. But Newell was not bad and Knipfel was good. Schweiger who was a walk on got a lot of snaps too...

1659456081421.png

From 2016 - 2019 over half of the snaps played were by Paul Roads recruits... makes sense in 2016 & 2017; but by 2018, 2019 it would have been good to see some of the new guys win those jobs.

In 2018, we got our best OL recruit under Campbell in Downing. He and Ross are still on the roster, Ramos transferred out this off season.

All of the 2019 class is still on the Roster. Hopeful Remsburg can bounce back and have his best season yet. Simmons/Hufford I hope either take some big steps forward or are beaten out by new guys. Not sure if Treiber will emerge or not... seems like with all the issues at tackle he should have gotten on the field last year but couldn't.

For the last 3 classes almost no playing time. Obviously, Miller got on the field late last season and got to play against Clemson. Ideally, Miller improves one tackle spot, Remsburg improves the other, Downing improves Center and we find two capable Guards from the rest... My hope is that Neal is a stud and wins one spot and Simmons improves and takes the other.

A few years ago I know they did a G/C flop when one got hurt and the best backup was in the other position. But I don’t think they tend to as much. I really don’t like moving G to T.

Last year they thought flopping guys all over was better than just plugging Miller in at T. They ran out of options and had to play him against the most athletic front ISU faced all year, and after getting settled in he was great in the second half. By the 4th quarter they were leaving him on an island without TE help.

And yes, Purdy was a terrific player and was tough as nails, but he was not good at climbing the pocket. There was a good example on a sack vs Clemson in the 4th.
I loved Purdy, but I'm really looking forward to a QB who isn't throwing from 12 yards or scrambling from 17 yards behind the LOS for a 2 yard gain on a crossing pattern.

It might be hard to analyze this without sufficient data from other schools. There might be a change in how or who PFF evaluates line play. I'd be interested in seeing the difference between ISU line play and the average CFB line play each year to weed out any effects that might be due to changes in evaluation standards/quality year over year.

There are clear trends within the data in terms of performance evaluation year-to-year (did all line play get worse in certain years or did evaluators changes). I would be interested in seeing data normalized.

It's also hard to really compare years when things change in terms of offensive philosophy. Are we expecting the O-line to do more or different things? Changes in philosophy or style likely would both cause and be caused by poor play in some way. It would be good to compare to more meaningful metrics like offensive output and team success.

It's interesting because our "best" o-line year was 2015 yet that team was 3-9. Our "worst" o-line year was 2018 when we were 8-5. Defense was a big cause of that. That said, we were a completely different team philosophically by the time 2018 rolled around. 2018 still had a higher yards per play offensively than 2015. A large part of that was Brock Purdy's 10ypa throwing the ball. 2018 had like 12 less offensive plays per game than 2015 but scored more. (This isn't due to defensive turnovers, because they were about equal.)

Yes... I tried to show this in the chart.

You can see that all of the offensive line play has a similar trend... So it does explain part of the dip from 2016 forward. But 2014/2015 we were above the Power 5 Average rating, since then we have been below the average. So, even accounting for the overall lower grading 2016-2021, you can see we performed below average.

You are right though, key is our performance vs. the average rather than just the raw grades.

Looking at the overall offensive performance, it is important to note that every other position saw significant improvements in their grading from 2016-2021. So, that explains overall performance improving while OL has been lagging.

At the 9:25 mark you see a great example. TE chips and the LT stonewalls the DE. The three interior guys destroy a twist or a stunt inside. The guy that gets the sack takes a terrible, path of least resistance route about 3-4 yards outside the tackle box and 11 yards downfield. The LT lets rides him downfield and wide. This should never, ever be a sack.

But there was also the play in the 4th where Purdy had a great scramble to convert on 3rd and long.

You just had to accept some mistakes from Purdy in exchange for some great plays. After all, sports are entertainment, and there's no disputing Purdy was entertaining.

The great scramble play was at the 8:10 mark

Also a good example of Purdy not knowing where his check down RB is. It's something that Park was really good at, and we saw it a lot from Dekkers in his TD drive against Iowa.

We should've been looking for Hall a lot more out of the backfield, but Purdy preferred to stare at Kolar and try to fit something into double coverage (which worked more than it should have. Thanks, Chuck).

I'm hoping that this will be the breakout year for the OL. Clearly last year there were a lot of injuries that caused ISU to play 5 guards for most of the season. We will see how things work out. I always thought it was a big mistake hiring a grad assistant as an OL coach. Especially for a team that struggled putting together a good OL. Hoping they will get better is all we can do at this point.
