Hesse and Nelson are senior defensive linemen. Stanley is the Hawkeyes' junior quarterback. He is only the second junior in Ferentz's 20 seasons as head coach to be selected to attend the media days event. Middle linebacker Josey Jewell got the nod two years ago.
The Iowa contingent will speak to the media July 24 at the Chicago Marriott hotel. Ferentz will kick off the second day of the gathering with an 8 a.m. news conference. The players will talk to reporters at 2:15 p.m.
Each Big Ten team brings three players plus a head coach to the event.
Stanley was an honorable mention all-Big Ten honoree last season, his first as a starter. He threw 25 touchdown passes.
