I think these posts are all hitting upon two very important facts:
1.) As Nebraska fans, we are happy with Frost and his coaching crew, and we know we have talent. We want to see that yield a great year and a great record, but we've endured 15+ years of disappointment. Even when Pelini had us winning a lot, we would get crushed by a Wisconsin or we would lose a title game by a fake second. It's hard to just shake those bad feelings.
2.) Added to that, as MANY analysts have pointed out, the Big Ten West is basically the "Wild West" this year. There are like 5 teams that could win it, conceivably. We're kind of the favorite right now, but you could say Iowa, Northwestern, Purdue, Wisconsin, or Minnesota and nobody would be too shocked. Well, maybe they'd be shocked if Minnesota won, but you know what I mean.
So, I voted for 9 wins, West Title, going to the Championship. I think our floor is 7 wins, and our ceiling is undefeated. And that's a WIDE berth to guess from.
