Assuming the general play calling, O-line, etc. trends continue. Nothing like bags for recruiting or assembling some impossible all-star staff. Also this is assuming Diaz is making the changes.
For me it is:
1) Encourage Blake Baker to look for another DC job. When Manny had more involvement, the defense looked much better. The guy is just collecting a check at this point.
2) Encourage Banda to look for another job. Recruiting has not been great and his time is up as a coach.
*Note: The above two are probably not as realistic given they have followed him and are his proteges, hence the 'encouragement to pursue other jobs'.
3) Fire Butch Barry. Our line is crap, talent or no talent. Many of us have been saying that Zion does not belong here, but I do think another OL coach would make him at the minimum better than this. Just too many issues to keep him. Donaldson blocks like a slob, Campbell hasn't developed at all, etc.
4) Tell Enos to open up the offense more or to look for another job. I think he's actually a very good qb coach, but the complaints about his playcalling are all 100% justified.
5) In response to the Baker firing, hire a full time ST coach/safeties or co-lb coach and make Patke only co-linebackers. Jovan Dewitt, the outside lb and special teams coach at Nebraska for instance. Has great experience at UCF, Army, etc and in his mid-40s.
6) In response to the Banda firing go after a guy like Fran Brown at Temple (their co-DC and like 8 years of secondary experience.), and make him co-DBs/DC (Rumph staying at cbs).
7) In response to the Barry firing, someone who doesn't change jobs every year and has successful track record with all conference linemen in smaller programs like Texas Tech's Steve Farmer (also successful at Utah State and Louisian Monroe) who's been a good line coach for over ten years.
