I have thought about this topic some. Husky fans like to say Lanning was out coached. Other than the wins, I can't really think back and go wow, great coaching there by Deboer. I am not saying Deboer isn't a great coach, I think he is. I just don't understand the narrative that the losses suffered by Lanning came as a result of Deboer having a better scheme or in game adjustments. I don't see the difference in either game being due to some form of Deboer superiority in coaching. Maybe my Duck lenses are causing a blind spot, but when I watch these teams play each other I don't conclude that one is better coached than the other.
If anything, I see that Deboer has a team with strengths in our weakness, that being primarily, the play of our DB's especially safeties.
I think time will tell the difference as each coach is faced with maintaining their winning ways. Who recruits and develops the better roster? Next year will give a really good idea as to which coach will be able to continue their winning ways.
