Iowa receiver Keegan Johnson hopes the experience he gained last season as a true freshman will help him make ever more progress next season. The native of Bellevue, Nebraska, appeared in 13 games last season and had 18 receptions, including two for touchdowns.

Johnson says one of the biggest lessons from last season was overcoming mistakes.

Johnson was part of a freshman class that saw several players earn immediate playing time and says the classes jelled quickly.

The Hawkeyes close spring drills with an open practice Saturday in Kinnick Stadium.
