Diaco was good at times, but he wasn't elite. The personnel we had in 2012 was amazing, I think any decent DC could have put together a winning season with that crew. Diaco struggled to game plan against an average Michigan team each year though, and he struggled with halftime adjustments as we witnessed from Navy. If BVG can come out with a healthy squad on defense next year and produce, 2014 will be forgivable. However, if teams are still racking up points on us, I wonder if they don't have his defense figured out and we need a new strategy.
