Lest ye forget, another DA bungle: losing Aaron Glenn, Ryan Nielsen, and Kris Richard

His inability to retain quality coaches is yet another reason why I'm counting the days until we have a new HC. That co-DC shenanigan was a big backfire, and the sign of someone who lacks conviction.
That isn't exactly fair or accurate.

losing Aaron Glenn, Ryan Nielsen, and Kris Richard​

Aaron Glen left because Dan Campbell made him DC.
Ryan Nielsen left to become DC in Atlanta
Kris Richard isn't even coaching this year. No reason given.

So, 2 left because they were made DC, and the other guy isn't even coaching in the NFL.

Let's face it, most of what DA did right was on defense. Imperfect perhaps, but the D is not the reason we can't win the division. If the offense could function, the D would be fine.
