At Big Ten Media Days this past week, Matt Rhule made the comment that if Nebraska were to play a game today that Tyler Knaak would be the starting right tackle for the Huskers.
Add that to the fact that Henry Lutovsky was one of three player representatives (plus his starting experience) for the Huskers at the media event in Las Vegas and I think we can start making some assumptions about the presumptive starting offensive line. This is all subject to change as injuries happen and players move up and down the depth chart. With that said, as of today this looks like the starting offensive line for the Huskers.
