He's going to have to be more vocal with the media moving forward. I'm not saying he has to do a 180, but he definitely cannot keep this style forever. His silence during the 2nd half of the football season did more harm than good.
I wish I'd heard more during the season, too. But just to play devil's advocate, isn't there a sound reason for the policy (that many ADs have) to make public comments only after a season? Let's say he made an exception this time and in, say, October, gave the OWH a strong expression of support for Bo's future at UNL. That would have quieted some of the fires this time. But then in future seasons he would either have to offer a similar expression for a coach or the media would immediately assume that the coach is on the hot seat. Conversely, if he sticks to the current policy he doesn't set a precedent that could come back to haunt him in the future.
I'm not an AD, or anything close to it, but I like the idea of clear and consistent policies, and it seems to me that SE was doing exactly that here. Even better -- he weathered the storm by resisting public pressure to make a statement. I think that says a lot about his steadfastness, even though the silence made me personally uncomfortable.
