That was a poorly officiated game to say the least. The worst that I can remember in terms of being one-sided but it should serve as a lesson to coaches and players. Don't leave the game in the hands of officials.
12 years later college football officiating is still shaky at best and will continue to be until the B1G and college football get their heads on straight and pay officials to be full time officials. This is particularly hurtful to schools like Iowa. The B1G usually sends their top crews to officiate the most high profile games which include Ohio St, Michigan, Penn St and Wisconsin. So unless they are playing those teams they get the lower graded crews.
