It worries me that we haven't heard any official word on this because of how desperately the field needs replaced.
Well, it depends on how you approach it. A real possibility is that they will be replacing the turf but nothing will be changing on the field. The logos, wordmarks, and multi-turf would all stay the same. Think about it, when they put new turf in before 1999, the big story was that it was moving from AstroTurf to FieldTurf. When they replaced it before 2005, the big story was changing the wordmarks up and using the multi-turf. So if they don't change anything, there's no real 'story' here so it'll be changed quietly and without any fanfare. Kind of surprising for Nebraska.
