Would agree with most of this at least.
Only positive prediction to add. (Strange as it sounds) I think we will miss Donald less that one might think simply due to the changes within the scheme Shula will make.
We have prepared for this for almost a year clearly and its futile to think we will try to replace AD man for man. So a small scheme change and D will focus on different kind of pressure. (As much as we will ALWAYS miss the best defensive player of my adult life. obviously)
Other than that I think this season entirely comes down to injury or not. Stay clear and we can go all the way.
