I was expecting the D to slide a bit, for sure in the beginning of the season.
Just not this far. Anytime a D has to learn a new system, they slide for a while in production. They just do.
Having said that, I disagree with Williams' and Fisher's philosophy on D - making it so complicated.
IMHO with the need to churn your roster so often, with so many players, I think you need to chose systems that are less complicated
I'm not saying to simply play vanilla, just not as complicated as I understand Williams' system is. JMHO.
