I think Diaco ought to be able to field a great team next year. We basically return everything except our OLine, and I can't remember ever having a bad OLine under Foley.
I wish I shared your sentiments. I am really concerned about the D. Losing Shamar Stephen and Smallwood is huge. I don't see anyone on the current team who can come close to replacing Stephen. He engulfed blockers and had surprisingly great lateral movement for such a big guy. Maybe Coach D can light a fire under some of our talented but unproductive linebackers to replace Smallwood, but that is no sure thing.
Our running game will continue to struggle if the line plays like last season (yes, even when Coach Foley took over, the running game was an adventure). This is a position, however, that can see huge improvement depending on the strides in the weight room from the younger guys. Casey makes quick decisions with the football which takes pressure off mediocre pass blocking. We have also yet to see a BCS back emerge.
The good news is there is raw talent on D that has shown flashes, especially in the secondary. And the receiving corps will be one of the best in the nation 1-5 next season in my opinion. Coaching will have a big impact on how well this team does, both in developing talent already on roster, and putting them in the best position to succeed. The fact that when he had to review the coaching staff he decided to only keep Foley, is a very good sign of Coach Diaco's decision making.
