The high school team I broadcast plays a system very similar to this zone defense. This year they were very successful and I saw a number of opponents look just like IU, completely unsure and hesitant when throwing passes. There were nights when it looked like it was a major accomplishment for a team to put up a terrible shot because that means they hadn't turned it over. Seeing IU with more turnovers than FGA for most of the first half made me think of Mt. Vernon.
