Interesting. Here are each coaches cumulative averages:
Offense / Defense
DM 24.2 / 25.125
SHF 22.3 / 26.9
DB 26.55 / 35.4
No coach has scored more than they surrendered. Babers has given us the best offense, and worst defense. Fix the defense, and... Some may argue needing the right players for his scheme. Others, more 3 and outs lead to opponents scores. Others a by product of tempo, without consistency.
For giggles, I compiled PPG with Dungey, and without.
With Dungey(2017):
Offense 29.11 PPG
Defense 24.88 PPG
No Dungey(2017):
Offense: 22.3 PPG
Defense: 54 PPG
With Dungey(2016):
Offense: 26.62 PPG
Defense: 31.62 PPG
No Dungey(2016)
Offense: 23.75 PPG
Defense: 48.75 PPG
The thing that stood out to me was 2017, with Dungey. Defense gave up less than Shafer or Marrone. Woot. Yeah, there are other variables that must be considered. It IS the first sample(only 75%) where we scored more than we gave up.
With Dungey out, the defense was abysmal. Yes, there were injuries there. The drop just seems too significant. I think the focus on the run game, is to avoid this kind of inconsistency going forward, regardless of QB. There is a 75% complete sample, that shows the system can work - even with a sub par run attack. The QB play can lead to a much heavier load on the defense. For me, I'd like to see improved run game, and an improved/less burdened Defense.
