"My family and I had been talking about it for the few days leading up to Coach Morgan coming to the school," Koehn said. "When he came in to meet with me and my dad, I just told him I was ready to commit and get it over with."
Koehn accepted a preferred walk-on opportunity at Iowa.
"UNI wanted me as a preferred walk-on as well," Koehn said. "Iowa State wanted me to walk-on. It wasn't preferred. It wasn't the same opportunity.
"I grew up an Iowa fan. They started recruiting me before my junior year. I really couldn't see myself saying no to them."
Freshman Mike Meyer of Dubuque joined the Hawkeyes as a walk-on last fall. He won the place kicking duties away from two scholarship players.
"He's good and it was exciting to see a freshman come in and take over the job," Koehn said. "It shows me that I have a chance to come in and compete for a job."
Iowa struggled on kick coverage last season. One of the issues was length and placement on kickoffs.
"(Iowa coaches) have told me I have a chance to come in and do that," Koehn said. "They said there's a chance they could split up the jobs (kickoff and place kicking). I'm going to try to be one of those guys."
Koehn said he recorded 45 touchbacks on 85 kickoffs last season. He connected on 13 of 18 field goal attempts, including a long of 48 yards.
Koehn is a standout baseball player at Solon. He's considering being a two-sport athlete at Iowa.
"The baseball coach (Jack Dahm) talked to me about joining the team this fall," Koehn said. "I'll talk to him again. But I'm not sure about doing both. Right now, I'm going to concentrate on football."
