Haven't heard a whole lot about the young o-line, but I forgot to mention the great reviews I have heard about the freshman OL, Joe Kleason from CDH. Apparently the coaches love his potential. I have to imagine he will be in the mix next fall as a freshman. Maybe not starting right away, but pushing for playing time at the least.
Haven't heard anything about Doehling, Field, Hoerchner or the two Nelsons, who are all redshirts this year. Hopefully there is some promise in that group too. With Koelln, Keller and Bondy all graduating this year, and Bakke apparently having to hang it up for medical reasons, we are going to be awfully young next season on the o-line depth chart. Both scary and exciting at the same time.
