Just because the line didn't move substantially doesn't mean there wasn't something nefarious going on. And by the way, I never claimed the game was fixed. I said there was something fishy going on. Hypothetically , if the refs were involved , there are plenty of things they could effect besides the game line.
As far as your assertion about the spread being off. No, I don't think the line was off. Because Utah was at home the line was closer to even as it should've been. Traditionally this is a one or two possession game by the end.
