When an AD remains so tight-lipped through most of a season with a question looming so large, I suspect we had better hang on every word. It is unlikely there will BE many words.
My guess is this is as good as saying, "Pelini WILL be here next year. UNLESS there is off the field behavior from the coach that makes us really question him or some legal problem."
In other words, I think Pelini is the coach next year. If that is the case, I will dutifully line up and support the man, hope for some other coaching changes, and so on. In fact, with the benefit of some time to cool off, I wonder if some new coordinator(s) would be the answer after all. If anyone can 'force' such a change, I bet it's a brand new AD. Gives Pelini an 'out' by saying, "Sorry, I had no choice. It was either you or ALL of us, including all your friends."
