By the (Advanced) Numbers: Duke

If Virginia Tech can keep Duke in check on 3rd- and 4th-and-short, the Hokies could pull the upset.

You may not know this, but if you wrote a (really terrible) book about Virginia Tech's football history against Duke, you'd probably have to divide it into two parts: Part I: 1937 - 1951 and Part II: 1969 - Present.

For the sake of good literature please don't write this book, but consider that Part I would consist of the Hokies going 0-6 and getting outscored 19-207. Anyone weird enough to keep reading would then see Part II deliver VT a 13-2 record and outscore the Blue Devils 453-171. Of course, the final chapter is a 10-13 home loss with a 387-198 yardage advantage capsized by four critical turnovers. That Duke also had four turnovers is made irrelevant by the final score.

The question on Hokie minds this week is whether, given a few more years, the 2013 contest would be grouped in a Part III about returned Duke dominance or just another blip in an increasingly lengthy Part II.

Let's try to answer that by starting with the computer rankings for each team:

A friendly reminder that the maroon dots represent the Virginia Tech rankings, while grey represents Duke's. Please, take a moment.

Since there is near universal agreement by the predicting computers that Duke is the better team, the predictions should come as no surprise:

The odds of a 5.5-point underdog winning are 35.2%.

Next is a look at any overall offensive or defensive advantages before drafting the opening to Part III of the book:

This is an interesting situation likely not previously seen in By the (Advanced) Numbers: S&P+ disagrees with the other computers. Although not all publish their methods, the standard for computer rankings typically utilizes either win-loss data or score data to rate teams; conversely, S&P+ and FEI use play-by-play data and are able to remove much more luck components to gain a better picture of who "won" between two teams. It would seem then that Duke's results thus far are likely not particularly representative of their ability to move the ball and stop the other team from doing so. In fact, on a neutral field S&P+ believes the Hokies are the better team.

Better hold off on Part III for now...

When Virginia Tech Has the Ball

Here is an explanation of S&P+ ratings, and FEI ratings. All statistics are now opponent-adjusted.

Who has the advantage in the passing and rushing game when the Tech offense has the ball?

While fans might be used to opposing defenses having the advantage, things are fairly close in this game and traditionalists will take solace in the Hokie rushing game being at a slight advantage to the passing game.

Now let's take a look at the FEI personality traits of the Hokie offense versus the Blue Devil defense.

Think of efficiency a bit like yards per play adjusted for opponent. Virginia Tech's offense is not very good at that, and it's sort of an important part of playing football. But hey, methodical drives!

The No. 89 Virginia Tech offense is closest in personality to:

  1. Kent State
  2. Hawai'i
  3. Penn State

The No. 13 Duke defense is closest in personality to:

  1. Washington
  2. Oklahoma
  3. Northwestern

When Duke Has the Ball

Again, examine pass-run comparisons first:

The big plays might sting, but Bud Foster has put together an elite pass defense, and despite disappointing point totals he has faced 5 of the top 25 F+ offenses in college football already. Duke will be the lowest-rated FBS offense played yet besides Western Michigan, who is rated four spots behind them. Wake Forest and Virginia are easily the two worst. Injuries aside, we may witness some real defensive dominance down the stretch.

As for personality traits:

With the exception of explosive drives, VT enjoys slight advantages across the board and a modest one on efficiency.

The No. 3 Virginia Tech defense is closest in personality to:

  1. Michigan State
  2. Arkansas State
  3. Air Force

The No. 37 Duke offense is closest in personality to:

  1. LA-Lafayette
  2. Central Michigan
  3. Arizona State

Special Teams

First we look at the Hokie's kicking units:

Used to bigger Tech advantages? Duke has the No. 1 special teams unit in the nation. But VT is still better at punting than the Blue Devils are at returning. When Duke kicks:

As bad as Tech is at returning kicks, kicking off is clearly Duke's weakest unit. Rather than risk injury it may be worth just giving the Blue Devils 3 points when they attempt a field goal.

Who To Watch Out For

  1. Freshman RB Shaun Wilson averages 9.22 YPC, 2nd in the nation. (Note to self: keep in preview and change "Freshman" to "Sophomore" next year)
  2. Senior LB David Helton averages over 10 tackles per game

Missing Anthony Boone? He is still the QB but has a QB rating lower than Michael Brewer this season.

Statistical Key to the Game

One area where Duke is at a disadvantage against VT is on third- or fourth-and-short where the Hokie defensive line has had much more success in stopping the first down (24th) than the Blue Devils have had at making them (87th). Keep Duke under 60% and win the game.

My Prediction

Let's not write Part III just yet. While it would be hard to believe we're still dominant against Duke, no one can claim the opposite yet either. Maybe Part III is a period of parity, or maybe we're in a two-year blip, Cutliffe bolts after the season, and Duke returns to cellar-dweller status.

I think the defense looks much less vulnerable than we've seen and we're looking at a low-scoring affair but ultimately win and do so in a way that gives us hope for the last two regular-season games.

Comments

If we can stop the run against Duke, which is normally BF's simplified gameplan for everybody, I believe we will win. Although they may have decent running backs behind a solid offensive line, I don't see Duke Johnson on their roster. Hopefully the similiarity in names doesn't lend anything to how their backs will perform against our defense this weekend. As bad as we are, I can't see us losing to Duke...again. Last year we had 4 turnovers and a handfull of missed fg's that would have won the game had they been made from a kicker that normally made those type of kicks. If the offense can generate any type of consistency and the D plays to their ability I think we win by at least 7, maybe more. If the defense is as dominant as they should be they should be able to blank Duke. However, a busted play here or there that has been their 'MO' this year has cost us just about every loss, save Miami (that was just a beating).

So will the D be able to keep the big plays from costing us the game this week? I hope so. If we lose it's going to be because of more of the same, O unable to do anything with anything and the D giving up just enough big plays to let the other team win, a la BC, GT, Pitt, and ECU.

Since I can't find a clip or gif or anything, just picture that scene in "We Were Soldiers" of when everything is going crazy in the middle and Mel Gibson is looking around says calmly in the midst of it all "...We're gonna win this fight." That's kind of how I feel about this week.

This is great stuff. Thanks for another great analysis. By this time in the season the amount of data available makes the comparisons and available data much more convincing. A couple things that stick out to me:

1. Freshman RB Shaun Wilson averages 9.22 YPC

Ulp! Im guessing 2 big run plays out of this guy that cause us heartburn. If we can stop that then we have a chance to keep Duke offense output very low.

2. With our passing D advantage, Bud's plan could be to try and really focus on run contain. It would seem it might not be a good idea to make them one dimensional running the ball, so run contain and big run play prevent is what I think Bud will do.

3. Statistical Key to the Game
One area where Duke is at a disadvantage against VT is on third- or fourth-and-short where the Hokie defensive line has had much more success in stopping the first down (24th) than the Blue Devils have had at making them (87th). Keep Duke under 60% and win the game.

Watch for play action or bootleg from Duke on these short yardage 3rd and 4th down plays. Earlier down run plays could set that up.

From this analysis and the fact that we have already played " 5 of the top 25 F+ offenses in college football", I just have a feeling we are a better match up against Duke than we have been against other teams. I see a VT win.

Cutcliffe may be the determining factor. How he dials up a response in the 2nd half to what VT does could change the game. Looking forward to this game. #Intrigue

Go Hokies!

Good analysis and write up, but I just feel like you skimped on the punting stats this week...

17-14 VT , Really like this prediction, this is the week the ship turns around.

Quick question on our continued F+/S&P ranking being higher than perception. You noted that we've played 5 of the top 25 offenses. Some others have noted that our success against OSU continues to skew our rankings. Would you agree that that one game causes some of this ranking?

I'm not sure how well this will paste here, but FEI actually breaks things down to the game level:

There are goods and bads about the OSU game...it was obviously the best overall VT performance of the year and 11th nationally, but in the FEI formula isn't carrying exceptional weight (GW). And while is was the best offensive performance to date (OFEI), both GT and UNC were stronger defensive performances so we are at least earning our defensive rating.

Thanks. My eye test agrees, we were great against GT and UNC.

I'd love to see us hold the remaining 3 teams under 14 points the rest of the way. We can win all three if we do that.

If we give up more than 14 points to Wake and LOLUVA I will be very worried that Bud might have a stroke.

I assumed he meant 14 points total for the three games. I'm thinking 7 to Duke, 3 each to the others.

Holding them on 3rd/4th and short sounds good, but if I'm not mistaken; Duke didn't convert a single 3rd down last year.
Anybody else notice we haven't won a game where we scored less than 31 points?
I'm modestly confident that we can win if they play with the same effort I saw against BC.
