I'm with Sid, actually. Watching the highlights and I just can't help but to notice the 'shoddy' looking turf. Maybe I'm over-analyzing it, but Nebraska's turf doesn't look like that. But, I've always been one to hoping that when the Vikings put in heating coils that the U opts to use the new font typeface in the endzone art.
I would suggest not worrying about it because it affects nothing and a majority of people don't even notice it.
