On October 19, 1985, the Iowa Hawkeyes were ranked #1 in the nation, while the Michigan Wolverines were ranked #2. Michigan came to Iowa City for a rare matchup of the top two teams in the nation. Iowa trailed, 10–9, with two seconds to play in the game. Houghtlin kicked a 29-yard field goal from the right hash mark as time expired to give Iowa a 12–10 win. Later that season, he made a 25-yard field goal as time ran out to beat Purdue, 27–24. Houghtlin was an all-
Big Ten selection after his sophomore season. As a junior in 1986, he missed a 52-yard field goal at the end of a 27–27 tie game against
Minnesota; however, a Minnesota penalty gave Houghtlin another opportunity, and he made a 37-yard field goal as time expired to defeat the Gophers, 30–27. Iowa's final game that year was the 1986
Holiday Bowl against
San Diego State, where Iowa trailed, 38–36, with four seconds remaining.
Chuck Hartlieb caught a high snap, and Houghtlin booted a 41-yard field goal as time expired to give Iowa a 39–38 victory. Houghtlin was again an all-Big Ten selection as a senior in 1987, eventually leaving Iowa as the school's all-time leader in field goals and points. ==Professional career==
