IOWA CITY, Iowa-- A humble, hardworking approach is the only way third-year tight end DJ Vonnahme knows how to operate. It's also the best possible way to stay off the hype train. It's an exciting time for the Vonnahme family. They are watching their loved one become a major talking point whenever Iowa football is discussed. Vonnahme started last season's fall camp as the fifth-string tight end and a walk-on. He was someone many believed could develop into a contributor down the line.
