Which staff do you have questions about?
Here's my list:
TRob - still has not shown big time ability as a DC and managing the rest of his staff. Thompson may have been the problem there so it is possible that, with him gone, and the injury situation cleared up, that things come together more. I'm still waiting for a dominant defense.
Scott - perhaps the most questionable hire. But if LB and secondary improves the DL will be asked to do a little less. But he was not a splashy hire to replace Thompson.
Hutzler - LB play has underwhelmed the past 3 seasons. But with Peterson and Krantz assisting (OLB and SAM) and the returning talent they should be improved this year.
The offensive staff may be the best we've had, but BMac has to show he learned from his mistakes last season. Against Michigan the year before last he found a weakness in their defense and kept picking at it until it worked. I think he did the same against Clemson this year. But he fell flat against UVA and the second half of UF and Akron. I am hoping for more consistency out of the offense. (some of that may have had to do with Muschamp)
