If he's healthy Levi Paulsen will move out to tackle, where he started in the bowl win over BC. The other tackle will be either redshirt freshman Kallenberger or senior backup Dalton Ferguson. Kallenberger is listed at only 282, but he got good reviews from the coaches last season and in spring ball. Just guessing that Ferguson backs up both tackles vs. the Huskies.
One of Banwart and Reynolds was going to start at OG anyway. With Levi moving to tackle for NIU both will probably start. Landan Paulsen could figure in.
Bagdropper had a good point above. If you are going into a game without your starting OTs, both of whom are good, it helps a lot if you are loaded with talent at TE. Look for a lot of two-TE sets and some three-TE sets to help out the tackles and still get one of Fant/Hock/Beyer open.
Run the ball, play the fullback and when NIU crowds eight men up front throw to the open TE or WR, or a RB out of the backfield.
No doubt the game against the Huskies just became more difficult, but Kirk Ferentz enforces the rules- not just when a player ends up on the police blotter. That's a quality most fans admire in our coach. At some schools the players would play the game anyway.
When the three starters and key backup line up on the field for the second game I suspect they will do some damage to their opponents.
