By the (Advanced) Numbers: Duke

The Hokies need an efficient yards per play to keep drives alive to have a chance at upsetting the Blue Devils.

As Hokie Nation endures the possibility of the bowl streak ending, and the reality of another disappointing season, the team is focused on turning the season around. Last season that seemed to happen against Duke...will it happen again this season?

Where the Season Stands

Virginia Tech is currently 3-4. The actual and predicted score difference and odds of winning each game are:

The odds of each possible regular season win total are now:

The chance to make a bowl is less than 40%, but far from gone. Perhaps the return of quarterback Michael Brewer will spark a run down the stretch?

Rankings and Computer Predictions

The computer rankings and predictions for each team:

I have no explanation for why this is so close. Virginia Tech has been mediocre at best, while Duke is the favorite to win the ACC Coastal division at the moment. But numbers are emotionless and this is what they say. The odds of a 2.5-point favorite winning are 57.5%.

Next is a look at any overall offensive or defensive advantages:

Duke is a traditional Virginia Tech squad — an elite defense being completely held back by a below average offense.

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?

The Hokies continue to be a better passing team than running, but it's of little comfort against a phenomenal Duke defense. Not only does Duke excel against both pass and run, but they are the No. 1 team in the country on passing downs. This is not a team that Tech wants to find itself in 3rd-and-long against.

Offensive and defensive line performance are compared using Football Outsiders' metrics:

Although it may not feel like it at times, the Hokies' offensive line has been average or slightly above average in each metric this season. However, much of Duke's defensive success has come from the defensive line which may not sack the quarterback at any especially high rate, but is a complete run stopper. This is NOT the game to get away from Travon McMillian on the ground.

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

If nothing else, the Hokies are balanced across all categories but unfortunately not better than middle-of-the-pack in any one of them. Worse yet, the Blue Devils are also balanced, but well above average.

The No. 81 Virginia Tech offense is closest in personality to:

  1. Arizona State
  2. Massachusetts
  3. Akron

The No. 22 Duke defense is closest in personality to:

  1. Michigan
  2. Temple
  3. Boston College

When Duke Has the Ball

Again, examine pass-run comparisons first:

Now that cold water has been splashed on Tech's hopes on offense, there is a ray of sunshine on defense. The Blue Devils aren't very good in any area on offense except passing downs — the strongest area of the Hokies' defense. Will either team reach double digits?

Offensive and defensive line performance are again compared using Football Outsiders' metrics:

Duke's offensive line does what they should: the create yards for their running backs, win the push, and keep their quarterback from taking sacks. Dadi may play an excellent game, but his first sack will be tough to come by.

As for personality traits:

Again the already-not-special Blue Devil offense is presented with a tough matchup against the Hokies. The biggest weakness in the Tech defense — explosive drives — is also the biggest weakness of Duke's offense.

The No. 54 Virginia Tech defense is closest in personality to:

  1. BYU
  2. West Virginia (yuck)
  3. Charlotte (?)

The No. 98 Duke offense is closest in personality to:

  1. Washington
  2. UTSA
  3. Wake Forest

Special Teams

First we look at the Hokies' special teams units:

As a whole, this is one of the better units in the country, but individually nothing stands out as exceptional. Additionally, kicking and punting have been below average.

When the Blue Devils kick:

Again the Blue Devils are fitting a traditional Virginia Tech mold of exceptional special teams. In this case, including the top kick returning unit in the country.

Who To Watch Out For

With such a weak offense and an efficient but unaggressive defense, Duke is less a team of stars than it is a well-coached unit that doesn't make mistakes.:

  1. The Blue Devils' offensive line. It is remarkable that Duke's offense isn't better given how clean they keep the quarterback, and how much push they can get on opposing defenses.
  2. Kick returner DeVon Edwards, averaging an incredible 39.7 yards per return across his 7 returns this far, including two touchdowns.

Statistical Key to the Game

Can the Hokies sustain any sort of offensive drive against such an efficient and effective defense? It's hard to see this game coming down to turnovers like Miami. Rather, it's a question of which team can actually move the ball for more than a few plays at a time and keep their defense fresh. For this one I'm looking at a bread-and-butter stat: yards per play. I think whoever can keep moving the ball will wear out the other defense and take the momentum in the game.

Statistical Prediction

Most of the numbers going into this include a Virginia Tech team with Motley at quarterback. What will the team play like with Brewer back in? It's the biggest question mark of all. Say what you will about Frank Beamer and whether it's time for him to move on, I can't recall any of his teams ever quitting, and I don't think this one is quitting either. The stats predict the Hokies will gain 110 yards passing and 212 rushing, and the Blue Devils will gain 163 yards passing and 211 yards rushing. If the stats are right, there will soon be 0-0 screen grabs of an elated Frank Beamer all over the Internet. Again.

I disagree. I think there will be a perfect companion to last year's WtF picture. This time, "who-farted Frank" with 0-0 because Slye misses a 52 yarder as time expires...

Yeesh. Seems like only last year that Duke went winless while we won the ACC Championship. Amazing how things change.

They started changing for Duke about the time they hired a coach named Cutcliffe. Guy is a great coach!

Virginian by Birth, Hokie by Choice

Really? It feelings like it was just yesterday that I was in the student section watching Duke beat us 13-10 at home.

Damnit, you math jinxed us again!

I can imagine no more rewarding a career. And any man who may be asked in this century what he did to make his life worthwhile, I think can respond with a good deal of pride and satisfaction:
“I served in the United States Navy"

ESPN had a blurb yesterday or Wednesday that said VT led the country in QB pressures at 31% of passing attempts pressured. That was really surprising, but it does seem like we are right there but not getting the sacks. (this may have been the article comparing the best CB's in the ACC, talking about Facysons advantage of a pass rush).

It was that article. Which was a neat read. Facyson has allowed 5 completions all year, 0 TD's, 0 passes of more than 20 yards, and teams are completing like 15% of their passes against him, which are all awesome stats.

This doesn't surprise me at all. It's why I argued that the recent thread here with a billion tangential stats that said the DL got pushed around vs Miami and is too small was just looking for a story that wasn't there.

Contrary to what many are saying because his fantasy stats aren't great, Dadi has played well this year.

I wonder if they normalized for Purdue not turning in that stat.

In another post there was discussion of Dadi not getting sacks, I thought it was because of his hands but nobody knew where to get the stats on pressures.

This is correct, these guys are always in their backfield.

This is going to be great for the ACC.

I didn't know the various pressure/hurries stats. I just knew what my eyes were telling me about Dadi.

Stats tell a lot, but sometimes they're not measuring the right thing and completely miss the real story.

Here's the story:
Facyson Top ACC corner?

___

-What we do is, if we need that extra push, you know what we do? -Put it up to fully dipped? -Fully dipped. Exactly. It's dork magic.

Who knew we had the best pass rush in the country? Didn't really expect to read that, although I'm pleasantly surprised.

"...When we step on that field, they bleed like we bleed and we're gonna show the world."
-Corey Marshall

Seems like Dadi is in the backfield every play with his arms around the QB, but his tackles are just so weak this year that they slip out.

Oh for sure. In the NC State game he basically bounced off the QB 3 or 4 times. He's had the potential to have some absolutely astonishing games number wise and just keeps coming up short up bringing the QB.

"...When we step on that field, they bleed like we bleed and we're gonna show the world."

I don't understand how our Overall S&P rating is higher than both our Offensive and Defensive S&P ratings. Shouldn't it be in between them?

Onward and upward

Not really...when you're in the op half your overall will tend to be higher than the average, and when you're in the bottom half the opposite happens. Just imagine the extremes...if you have the #1 offense in the country and the #10 defense, chances are pretty good that you're #1 overall because the 9 teams better on defense are likely to be even more than 9 behind on offense. It's tough to be really good at both. There are obviously exceptions, but this is generally the case.

Say what you will about Frank Beamer and whether it's time for him to move on, I can't recall any of his teams ever quitting, and I don't think this one is quitting either

I dunno, that 2003 team still haunts my dreams.

+1 for the 2003 team. A lot of similarities with 2015 when you think about it...

Inconsistent offense (2003 run game was MUCH better), average defense with weaknesses at LB, key injuries, and lack of depth, questionable coaching (the whole Randall/Vick fiasco).

Also, a lot of folks on the message boards wanted Foster/Beamer fired in 2003 because their schemes had been figured out and the game had passed them by. A lot of folks felt that three down years in a row was an indicator that the team would not be able to recover with Beamer at the helm and we needed some new blood to turn the ship around lest we endure mediocrity forever.

Deposit whiskey, receive wisdom.

We went 10-4 in 2002. I was on campus that season and the general feeling was elation over 10 wins in what was supposed to be a rebuilding year with a new quarterback. I don't know what message boards you frequented then, but they were not at all indicative of the mood on campus. In fact, this is the first timeI have heard anything of this sort from that time period, considering this was right around the time we were concerned about Frank leaving for the UNC job.

The Hokies need an efficient yards per play to keep drives alive to have a chance at upsetting the Blue Devils.

This statement makes me sad.

The two most frightening points in this article

The No. 22 Duke defense is closest in personality to:
3.Boston College

and

The No. 98 Duke offense is closest in personality to:
3.Wake Forest

I told him I’d crawl on my hands and knees to be the DL coach at Virginia Tech. Now, all of a sudden, I’m sitting in this chair and I told him I’d still crawl on my hands and knees to work here. I just want to be here.
JC Price

Although, to be fair, we didn't really struggle with Wake's offense. The only thing our defense could have done better that game would have been to put up points. Holding your opponent to a goose egg is pretty high up there as far as defensive accomplishments go.

So, basically, we need our defense to put up points to pull this one off...

And Wake beat BC, so...I'm not really sure what that means.

So based on our performance against those offenses and defenses last season, we'll win 31-0? I'll take it.

If I know one thing about Hokie football it's that we have an uncanny ability to take an opposing teams weakness and making them look like they lead the nation in that category for whatever reason.

"Upsetting the Blue Devils"

Sorry man didn't read a lick. That pretty much puts everything in perspective. We are talking football? Right?

Even when you get skunked; fishing never lets you down. 🎣

A sampling of team's we'd likely be an underdog to right now based on average rating:

Memphis
Toledo
Temple
Duke
Navy
Utah State
Western Kentucky
Appalachian State (!)
Bowling Green
Georgia Southern

I'm glad we're not playing Bowling Green this year.

Or any of those teams, for that matter.
