Beyond The Box Score: 'Big Play' Scoring, Texas 2007
There's been lots of chatter lately about Texas' lack of proven playmakers on offense: I discuss it in the annual, it's been a topic here at BON, the Barkers have been on it, etc. With Limas Sweed, Jamaal Charles, and Jermichael Finley all gone this year, it's a pressing concern.
Out of curiosity, I decided to chart Texas' scoring drives during conference play in 2007 to see what kind of scoring plays and drives our offense-produced points were coming from. With a hat tip in the post title to the fine work being undertaken at Rock M Nation, Data after the jump.

The chart below shows each of Texas' 2007 drives which ended in a touchdown, sorted by number of plays in the drive, number of yards covered, type of score, and yards covered on the touchdown play:
If we break down Texas' touchdown drives by number of plays, roughly grouped in fives:
Without context, the numbers don't mean much, but take a look at Texas' scoring drives that ended in field goals (again conference-only):
And the light comes on...
Here's what I'm seeing from the above:
* The raw numbers - even ignoring a potentially disastrous last three downs - strongly suggest that big plays are involved either in the scoring or the drive that leads to the score.
* Even if you took Texas' drives that ended in touchdowns and tacked on three downs of no gain at all, you'd wind up with a higher per-play average than those drives that ended in field goals - further rough evidence that big plays have a meaningful role to play in a lot of touchdown drives.
* The discrepancy in yards/drive for scoring series that end in a TD versus a FG suggests again that the big play is a factor in 6 versus 3 points.
* Without going deep into the play-by-play data, we can't exactly draw any big conclusions here, but this rough and dirty look at Texas' 2007 season begs a further study on the role of the big play in drives that end in TDs versus FGs. For a drive that included a big play but left a team short of the goal line, it shouldn't (in theory) matter that a big play got them there, but a comprehensive data study might prove otherwise. One big question I have after reviewing these numbers is whether a team is more likely to score if it gets to the opponent 10 via a big play versus a 12-play drive.
* As always, sample size caveats apply in a big way. This is one season, and one team. But as noted above, it raises some questions worth answering.
* What, if anything, does it mean for Texas in '08? Hard to say without answers to the aforementioned questions, but I think it provides soft confirmation that the concern about big plays is properly placed. The worst news? Jamaal Charles meant a LOT to the 2007 offense. The good news? In terms of matching 2007's offense, we can almost ignore the loss of Finley and Sweed, who were non-essential factors in Big 12 play in 2007 (for different reasons).
* One final thought: I'm going to replicate this study for 2006, on the hunch that we're going to see Limas Sweed play the role that Jamaal Charles played in 2007. And if I'm right, we'll be left to wonder what might have been with a healthy Limas last fall. Texas fans enjoyed one peak year from each player; my offensive optimism last season was built on getting gravy from both. So it goes...

Keys to the Game
Doesn’t Mack Brown keep track of how many explosion (I think that is his term) plays the offense generates and the defense generates?
If anyone has the data associated with Brown’s keys to the game, then I would be happy to run a regression analysis to determine if the keys to the game predict outcomes like points scored, points given up, and margin of victory or loss.

I'm encouraged
And surprised. I wouldn’t have guessed that Quan’s name was called so much. I regard him as a reliable receiver with good hands, but it looks like he has big play ability. I’m also encouraged by the number of short yardage touchdowns Vondrell punched in. It’s great to have a super-speedster like JC, but it’s equally important to have a guy that can road grade the ball against goal line-D. The loss of JC will hurt . . .someone is going to have to step up. My vote is for some option plays involving Chiles, McGee, DeSean Hales, two tight ends, and receivers that can block downfield.

Consistency
First off, how do you expect me to read that list of figures with Brooke Daniels waiting there in the next article?
...
Now that I’m back, what jumps out to me is that we clearly lacked a consistent offense last year. We rolled the dice and sometimes we came up winners, but without the big play we could just not get the job done. I take this as an indictment of the offensive scheme in general and poor line play in particular. The line may get better this year, but will the offense?

Line and offensive drives are most definitely related
I think last year when taken in comparison to other years would look more streaky, relying on the big play.
I dont doubt that big plays pump up the team, demoralize the D, and help the team finish off in touchdowns, but if I had to guess, I would think that it was magnified last year, with JC going nuts when needed, and the rest of the team being fairly stagnant.
Interesting read, and Id like to see how the trends match up against 2002, 2003, 2004, and 2006.

How many drives
include sacks? Sacks can really disrupt your offense and are a killer in yards per play.

I was shocked
but the average rush/pass yards per TD. I thought it was wrong at first, but a quick count showed 19 TDs less than 20, 15 more. So, JC’s long runs had a great impact on that average. That string of six of seven TDs, the least being 18 yards, wrapped around a 20-yard pass to Finley, averaged nearly 41 yards per.
That does indicate a rather feast or famine situation. The number of long drives, 11-15 plays, tends to confirm that; the accumulated inefficiencies tend to show up on longer drives. However, those types of drives are the most difficult (and valuable) against tough defensive teams and that is exactly where we had problems in our losses.
Nice work.

Cause for concern or optimism?
I think the post nicely wraps up what many of us have held as the single biggest concern from an offense perspective. Last year, the ‘horns were unable to sustain long drives without an “explosive” play. This is a problem. You cannot expect that when you go up against decent defenses you will be able to generate enough explosive plays (1 or 2 per TD drive) to win. Instead you have to have a versatile offense with the ability to wear other teams down with a complimentary pass/run attack. So, the first cause for concern is the reliance on exlosives to score TD reflected in the yards per play ratio of TD and FG drives.
The second concern is that JC, our primary gamebreaker is gone.
While its obvious that JC will be missed due to the desire for big plays, I also believe that we relied on JC’s big play ability because he was not a grind it out style of runner—hence the feast or famine mentality. To sustain long drives, you must be able to consistently pick up 4-6 yard gains. These pick-ups make 2nd or 3rd down manageable distances that maximize your ability to draw upon all your weapons. While I’d be curious to see the stats of times we picked up 4-6 yards via the pass versus the run, my hunch is that we relied on the short yardage passing game to pick up these small chunks of yardage more than most teams. Passing obviously has a lower success rate than running in terms of % of passing plays generating postive yardage. Combined with a young offensive, and an underclassmen at QB this inevitably led to INTs, QB scrambles, sacks, fumbles, etc. Therefore, the ‘horns approach last year could be characterized by periods of chaotic production sandwhiched between periods of inability to move the chains.
However, this should not all be reasons for pessimism, instead there could be some silver lining. First is that the line should be improved and thus minimize the negative yardage and TO factors. Next, Vondrell’s running style is better suited to pick up 4-6yards on the ground than JC’s while still possessing enough speed to take it to the house on occassion. Finally, considering that Nate Jones really came out of nowhere and that Jermicheal was less of a factor than we thought he would be the WR/TE situation is really no worse than it was last year so one could expect at least the same level of production.
Ultimately, the baseline is there for this team to with 7 or 8 games. Along with an improved defense, winning 9 or 10 games will require someone stepping up in a big way between Colt, McGee, and/or one of the young receivers.

Looking Further Into This
Since Im on my lunch break…
I was thinking about this, and touchdowns are always difficult to look at in my opinion. I mean if Charles busts a 75 yard touchdown, does that really mean our offense was running better, or does it mean something happened that cause an opening, and he could have scored from 5 yards out, 50 yards out, or even 500 yards out (if possible I mean, you get the idea).
The yards on the touchdown therefore in my opinion dont really count toward evaluating the offense. If you want to know how well the offense was working, it could also be useful to see how they set up that touchdown. Is the difference between a FG drive and a TD drive then if that home run play opens up? If coverage is blown or Jamaal shakes one extra guy? Or is the offense really working better on one rather than the other?
To attempt to get an idea about this, and since PB provided the numbers, I took the yards gained on the drive, and subtracted out the touchdown play’s yards.
This gives us a number representing what the offense did right before it scored a touchdown.
Average Yards Before Touchdown: 47.2
Yards per play Before Touchdown: 6.56
Now, looking closer at the field goal drives, one should be eliminated from that list. The 40 yarder against OkState came at the end of the game. Further conventional offense in this case was not an option. The aggie one was at the end of the quarter, but seeing how it was 4th and 2 at the time, I think its safe to leave this one in.
This takes a poor sampling size, and makes it damned near ridiculous though, but just for sake of argument, here are the revised numbers with that case removed.
Avg Plays: 9.33
Avg Yards: 53.5
Yards/Play: 5.73
FG Length: 38.67 (Minus 17 yards means average drive ended on the 21.67)
That OkState FG drive was right at the averages, so it didnt change the numbers much.
The last thing I wanted to look at was field position. On the FG drives, our best starting position was on the opponents 34, with an average position at the 24.8 yard line. So I took the TD data, and took it down to a subset, to include only the drives that started at the 34 yard line or worse. Those drives gave me the following numbers:
Avg Plays: 8.77
Yards: 79.05 (Avg position then starting on the 20.95 yard line)
Last Play Average = 20.4
Yards/Play = 9.01
Yards Before Touchdown = 58.64
Yards/Play Before Touchdown = 6.68
Again, the sampling size is pretty small, so all of this can be taken with a half of a salt grain, but heres some thrown together conclusions for discussion anyway.
1) First off, average yard line for field goal is damned close to the average length of a touchdown play. The amount we came up short of a TD equaling the amount we usually got for a TD seems to imply that the big play is the difference maker. If that hole opens, we score, if not, we fall short and settle.
2) Field position seemed to have little impact our TD drives. The stats are surprisingly similar between the long drives, and the easier ones. However I do think its worthy to point out that no FG drive started with good field position. Perhaps its a consolation that we didn’t settle for field goals on scoring drives from inside the opponents 34. Of course we didnt look at missed FGs, turnovers, failed drives, etc… But whatever, I want to hang my hat so I am.
3) Texas on the entire season had a yards per play average of 6.17, which is right smack dab in between the yards per play before a touch down, and the yards per play before a field goal. Perhaps the offense was working less efficiently on those drives, or perhaps there just more big plays within the TD drives that jump up that average.
4) I also wonder what these numbers look like on other teams, particularly those numbers discussed in point 1. Is this a usual occurrence? Or should there be more of a discrepancy between what you score on, and what you have left to go on field goals?

the other side of the coin
PB: Your touchdown drives chart is insightful. Here’s what jumped out at me: The HUGE number of long scoring drives, whether they took one play or 17, tells me the DEFENSE was every bit as porous as the critics charged. Maybe the offense was less to blame than we have assumed.
The talent issue was pointed out vividly when just one of seven senior starters (Frank Okam) was good enough to be drafted. Three others were FA signees. I wonder if any Top 10 team in decades has had seven senior starters on defense, only one of them good enough to be drafted.

Easy points are the name of the game.
Honestly, you could say that about any sport. Teams can grind out points at times, obviously, usually the team with the largest number of easy points (for football, that means big plays…for basketball, it would mean fast break points or maybe wide open shots) wins. That was one of the initial thoughts behind my Points Per Play (PPP) measure, and it’s starting to ring true with correlations to wins as well (I have a post about that coming up this weekend…I know, you’re a-twitter just thinking about it!).
