To the Booth: Buffalo and SDSU By the Numbers

By Chad Peltier on September 5, 2013 at 11:15a
Google didn't turn up any images of "Jordan Hall running over SDSU"... yet.

Because of you fine folks who volunteered for the charting project, I (and any of you) get more data to play with each week this season. It'll allow us to examine and reexamine some of the common memes from the previous game – "Was Decker beaten on almost every play? Did the Buckeye offense fall asleep after the first quarter? Do the Buckeyes have anyone to throw to?" – with some empirical evidence. 

While I don't have charting data for our opponents (yet), I'll also provide some statistical context for the game you'll be watching in the next two days. This week it's San Diego State University, who many thought would be a tricky opponent – that is, until they lost 40-19 to FCS Eastern Illinois. Whoops. 

Charting Buffalo

One thing Zach Smith has harped on this offseason was increasing yards after catch (YAC):

"Philly was the first to say that for however many catches he had, the fact that he didn't have 1,000 yards receiving, he even said that's a joke. I mean, what are we talking about? He's much better than that."

Buckeye receivers could stretch the field (Devin Smith), have high catch rates (Philly Brown), and block well (Evan Spencer), but few had the wiggle room to turn short catches in to big gains. The problem here is that Braxton's completion percentage was far higher for short passes

Receiver Air Yards Yards
D. Smith 47 47
Wilson 0 18
Fields 25 25
Spencer 5 10
Fields 7 7
Brown 8 8
Smith 3 9
Brown 10 17
HALL -5 1
FIELDS 21 21

Enter our new crop of freshmen playmakers. Only Dontre had an opportunity to show his skills against Buffalo, but he was one of the few receivers with a high yards-after-catch as well.

The table to the left shows what receivers did after making a catch. "Air yards" is the distance in yards that the ball was in the air, while "yards" is the total gain on the play. Subtract "air yards" from "yards" and, voilà – yards after catch.

This is only through three quarters of play, but it demonstrates that Dontre was almost the only receiver to gain any YAC against Buffalo.

Sure, Philly, Hall, and Heuerman had a few decent runs after catching the ball, but the Buckeye offense will certainly be looking for more than just one swing pass per game go for a high YAC. 

The data also shows that Braxton is still probably most comfortable throwing shorter passes, as almost all quarterbacks are. Braxton only attempted two throws for more than ten yards through three quarters last week (albeit with improved mechanics!). 

I then took a look at third down playcalling. Braxton did the majority of his drop back passing (without play action or packaged run/pass option) on third downs. Of the Buckeyes' twelve third downs (58% success rate), there were only three designed runs (two inside zone reads and one Dave) and two scrambles from Braxton – the other nine were short to intermediate passes. 

Further, two of Braxton's three sacks came on third down, which is what we might expect given the higher number of drop-back passes. 

Some quick hitters from the charting data:

  • Blitzes were fairly effective against the Buffalo offense. Rushing six on defense severely rattled Licata, leading to multiple errant throws (looking at you, Joey Bosa). Only the backup QB, Zordich, had any kind of running success against the 6-man rush.
  • The linebackers and Reeves received the most "minuses" on defense – primarily from reacting slowly or overrunning plays/getting out of position to make a tackle.
  • Decker had more plusses than minuses, but all minuses were for pass blocking against Mack.
  • In general, the offensive line responded well to five rushers but couldn't handle blitzes of six or more defenders. We will have to watch in future weeks whether defensive coordinators sell out on blitzes (especially on third downs) because they don't fear Miller's passing game. 
  • Miller's throwing mechanics were much improved, especially in the first half. This showed by his pass accuracy, which included thirteen "dead on," three "catchable," and only three "bad" passes. 
  • Packaged plays are somewhat difficult to identify, but the charting volunteers found three definite packaged plays – one of which Braxton saved by pulling down and scrambling. 

The charting project data will only get better with more practice and more contributors, so go volunteer to chart the SDSU game

Here's to Heuerman and Vannett getting more targets against SDSUGreat catch rates, but both could improve their YA

Looking Ahead to SDSU

There's no way around the fact that SDSU lost by 21 points to Eastern Illinois last weekend, but I will say that the team wasn't terrible statistically despite the loss.

It's only one game of data, but SDSU is just 61st overall in F/+ standings, which is actually in front of teams like Auburn, Cal, and Minnesota. 

The problem for SDSU was turnovers – all five of them – and three and outs. A third of the Aztec's eighteen drives failed to gain ten yards and that doesn't include several other drives that gained more than ten yards, but still resulted in a turnover. 

Their offense ran an astounding 99 plays, but at only a 4.44 yards per play average.

Yards per Play Points per Play Yards per Point
4.44 .19 23.16

These are not good numbers for the SDSU offense, but they're actually slightly better than Buffalo's last week. 

Based on the data, it's unfair to say that SDSU is terrible, just as Buffalo wasn't terrible. What's key is that the Buckeyes keep the peddle to the floor and cut down on mistakes so that this game becomes a blowout even if SDSU's quarterback Dingwell doesn't throw four interceptions.

To be fair on the YACs,
Devin Smith caught one in the end zone
Chris fields caught passes in tight coverage, had to dive for the catch, and were in the end zone.
If this were the NFL, Chris Fields would have had more YAC

"Miller's throwing mechanics were much improved, especially in the first half. This showed by his pass accuracy, which included thirteen "dead on," three "catchable," and only three "bad" passes."
This is a stat I want to keep an eye on, because I felt like a few of Miller's passes required the receivers to dive, jump or otherwise didn't put them in a place to continue up field smoothly and led to easy tackles. To use lame commentator talk, "he wasn't throwing the receivers open".

This is one where I am hoping to give more detailed instructions for the future reviews. I think we may have been giving Braxton a little more credit than deserved.

I noticed there was the Devin Smith TD where he threw it where only Smith could catch it. Then there were times where Smith and Brown had to dive for catches, Browns was called back on a holding penalty. Couple of times he hit a guy in the chest when he could have led him to the outside or inside to turn as it was caught to turn up field instead of getting nailed after/as they caught it. Then there was the complete miss of a wide open Smith and one over throw on the sideline where he had the CB beat that both could have been TDs if Miller hits the throw.

This Charting Project is an awesome new feature.  I wish I had the time to contribute to the effort.  I will be a consumer of these stats, though.  Thank you, thank you, thank you.

In old Ohio there's a team that's known throughout the land...

I hope you get more and better data from the project going forward. I hope we can fill in the Buffalo game better eventually too, maybe the offseason. But I think having a Monday off afterwards helped a lot of people contribute and get the data entered early in the week. That is a luxury we won't have this week, but hopefully the volunteers will get better/faster/more accurate.

This is only through three quarters of play, but it demonstrates that Dontre was almost the only receiver to gain any YAC against Buffalo.

Umm ... the data doesn't show that. In order, from the posted chart:
Spencer - 5 YAC
Smith - 6 YAC
Philly - 7 YAC
Heuerman - 7 YAC
Smith - 3 YAC
Hall - 6 YAC
That's 34 of the 52 YAC from the chart.  (>66%)

A better way to say that would be "significant YAC against Buffalo." Sure, 3-5 YAC is good, but Meyer was always looking for 15+ YAC explosive guys.

This is some of the best information I have seen from this site.  I'm glad there are other people that have time to chart this all out.

I can only remember three passes that if they were placed where they should have to gain extra yardage. I hope he improves greatly during the season.
