I think the main thing this year is to hope that Mills doesn't get injured. If he does we may not be able to replace him, albeit that both Quaid and Benson have looked ok in practice. Imho, we can't have a great year unless he is on the field and starting every game. Having a roughneck BB makes all the rest of the O work so much better.
Why no emphasis on D, you ask? Two reasons. First, I think we'll be improved marginally, even if nobody particularly steps up their game. Second, I've been hoping the D would come around for some time now and it hasn't happened. A good year has been slightly below average. Oth, if the O is clicking, then that's all we need to do pretty well. If we can get to an average D it would help, but what we really need is an O that is working.
We'll see soon enough.
