Is Manny a Good DC??

Now that the dust has settled, as much as I disagree with the moves (or lack thereof), we have to live with what we've got, so I wanted to take a harder look at Manny's performance strictly as a DC.

The sentiment here from most, as it seems to me, is that he sucks overall as a DC. I've read post after post that all have these things in common:

1. We get crushed by every good team we play
2. We make average offenses look great

So, I decided to take a look at 2016 - 2018 and see how he stacked up. Now, opponents YPP is not the best indicator in the world. No metric is. But it's a very good indicator of success. If you look, year in and year out, and the defenses people feel are the best, they are at or near the top in YPP allowed. So I took a look, and frankly, the numbers are staggering in Manny's favor. What I wanted to see is not only what the total YPP allowed was (I think we all know, for better or worse, that overall they were very good those 3 years when looking nationally), but how did we compare to the teams we played. Again, the sentiment here is we can't stop good teams, and bad teams look better when they play us. Well...…...those of you who feel that way probably aren't going to enjoy what the data shows.

-- In 2016 - 2018, we played 36 games vs FBS teams. Of those 36 games, we held our opponent under their season average in YPP on offense 30 times. That's 83% of the time. 83% of the time, when Manny was the DC, the team we played had a BELOW AVERAGE game on offense. That's not bad.

-- Of those 30 such games, 21 of them, we held our opponent to close to a FULL YARD below their season average. If you're not aware, that is a MASSIVE difference. A full yard per play is worth probably 50+ spots in the national rankings (6 YPP vs 5 YPP, etc). So in 21 of 36 games played, the defense held our opponent to almost a full yard less than their average (-0.95 and up is what I found).

-- Of the 6 games that the defense gave up MORE than the opponent's season average, only ONE of those times was it more than a full yard. 2017 vs Virginia, a game we won, but one that lives in infamy on this site. The others: 2016 VT when the whole defense was hurt (0.93 higher than avg), 2016 Notre Dame (0.06 above avg, basically a wash), 2016 Duke (0.15 above avg), 2017 FSU (0.28 above avg), and 2018 Boston College (0.07 above average). So even the games we were worse than average against that opponent, most of them were barely worse.

-- I'm not trying to skew anything here, I'm trying to project this objectively. So what about the offenses we played? That's where one could make an argument against what I've presented above. 2017, we faced a lot of good offenses. 7 of the top 41 offenses. Of those, the defense held 6 of them below their average. The only time they didn't, Notre Dame that was mentioned above, they only got 0.06 yards above their average. So we faced a Top 41 offense more than half the games, and almost every single time, they were below their average against us. 2017 and 2018, we didn't face a lot of good offenses. Only 3 in the Top 51. However, of those, we held ALL 3 to well below their averages. ND, GT, and Toledo. 2018, only 4 offenses in the Top 44. But again, all 4 were held below their season averages.

I will post the spreadsheets below, but the bottom line is, as much as you want to say the defense sucked and Manny sucks as a DC, the data is overwhelmingly against you. We do not face elite offenses week in and week out, but literally every single time except 1 that Manny faced a Top 50 offense, he held them under their season average. Again, doesn't mean the defense is lights out every week. We know we had some performances that left a lot to be desired. But for 3 years we all said "If we just had a good offense to pair with Manny's defense". Well, for better or worse, we're gonna get what we wish for.

We will find out week 1

LOL. Stop. You are the king of trolling, and I mean that in a good way. You're elite. But the only thing we're gonna find out Week 1 is how far behind Alabama we are. And the answer is probably considerably behind. We're going to find out how good he is and how good the team can be when paired with a good offense over the 11 weeks after that one.

Did you account for the offensive woes that we had when he was DC? I remember our defense being out there for a lot more minutes then the offense.

Not defending Manny, just pointing out that if we can improve on our offensive efficiency, 3rd down conversions and time of possession, it can only help us moving forward.

Manny the DC was a good DC. He wasn't perfect, no DC is, but he was good and produced defenses you could win with. Richt unfortunately gave him nearly zero help offensively.

Can Manny the HC running the defense reproduce what Manny the DC did while maintaining the team in the HC role? Hopefully so since that is the way he is choosing to go.

If Manny can reproduce those defenses, then he may have some success, but we will have to wait and see. Given the recent history of this program, the coaches we have trotted out, and more, I'm sure we'll find a way to improve the defense and then invent a new way for ourselves to lose to inferior teams.

Not defending Manny, just pointing out that if we can improve on our offensive agencies. 3rd down conversion and time of possession, it can only help us moving forward.

No, there's no way to quantify that statistically, but I think all of us who understand the game and follow this program realize that the offense and special teams didn't do the defense many favors.

Great post. I remember seeing similar to this in someone else’s breakdown of just the 2018 season. Pretty crazy that 3 of the 6 games came in the losing streak in year 1 when we had a ton of injuries. 2 were basically a wash and 1 that we won.

Can we do this analysis for Blake Baker the last 2 years?

Only 2 of the 6 games came in that losing streak in 2016. We lost 4 in a row, the first 2 being to FSU and UNC where the defense held those 2 teams to a full yard below their season averages. The next 2, the defense was not good. VT it certainly wasn't with half the front 7 out and then the next week at ND, overall it wasn't terrible but they got off to a fast start and we could never catch up.

I will look at Baker as well.

Well said OP. I appreciate the data being laid out like this. Bravo to others for pointing out the negative implications of 3 and outs on offense and the impact on defenses too. We run a very fast paced offense that is no friend to the D and their chance to rest.
That being said, I hate all of your contributions for giving me hope that this will work. My logical side says no way. But the analytical and emotional sides say anything is possible.

Excellent analysis! Thank you for providing a facts-based, unbiased, and data-driven overview.
 
Only 2 of the 6 games came in that losing streak in 2016. We lost 4 in a row, the first 2 being to FSU and UNC where the defense held those 2 teams to a full yard below their season averages. The next 2, the defense was not good. VT it certainly wasn't with half the front 7 out and then the next week at ND, overall it wasn't terrible but they got off to a fast start and we could never catch up.

I will look at Baker as well.
Yes my bad 2 in the 4 game losing streak. That VT game we had Standish Dobard and Terry McCray playing DE iirc. Won 3 of the 6 games. The other we lost but the spread was irrelevant.

People always went back to getting blown out by Clemson and Wisconsin as why the D was bad in 2017 but those games were just gifted by turnovers from Rosier. I also expected the 2018 Wisconsin game to be the worst of the 3 years before I looked. That one surprised me because I remember the D getting gashed but I guess it was just Jonathan Taylor because they did nothing in the passing game.

Also glad you looked at YPP instead of points or even total yards because our offense and STs had been atrocious through most of that time. That’s where a lot of stats got skewed but you can’t fault YPP.
