This is something I should've posted weeks ago. Big Ten Network Football personality, Gerry DiNardo was in town during April for a sit down with Iowa Offensive Coordinator, Greg Davis. At least 35 minutes of footage was shot for a piece that aired for 6 minutes. Two plays were discussed, and the variations from each play. It was explained how the different offensive positions play into each scheme, and Davis took time at the chalk board for added insight.
At the beginning of the interview DiNardo asked Davis, a veteran of the collegiate coaching ranks, how important video is to the college coach. This was a sampling of their Q&A, but well worth being published somewhere.
