Again, I don't think from the outside looking in (non-Husker fan) there's much to get worried about. All the things that made Vegas give our 2017 pause in year 3 of a coach coming off a 9 win season are still there. New QB (with less experience, we will be playing someone who hasn't started a college game before), new defensive coordinator, new head coach who bring a new offensive coordinator.
As fans I have no problem with our optimism, but there will be some bad times this season. This staff is all about rebuilding confidence. They started in the weight room, then there's some quotes that are coming out where they are really building these kids up and giving me some pause. There's some work to do.
When times get tough this year (and they will), the optimism and positivity in the locker room will come in handy. Coach Frost and his staff have a road map for how to take a losing team and build it into a winner.
