IOWA CITY, Iowa (AP) – Iowa junior Micah Hyde will start the season as a safety, according to the latest depth chart for the Sept. 3 opener against Tennessee Tech.  Hyde, who played his first two seasons at cornerback, will start at free safety with Collin Sleeper listed at strong safety.  Greg Castillo has earned a starting nod at cornerback in place of Hyde, and sophomore Christian Kirksey is starting at linebacker.  The Hawkeyes will need another week of practice to sort out whether Thomas Nardo or Dominic Alvis will start alongside Mike Daniels at defensive tackle.  Quarterback A.J. Derby and John Wienke are listed as co-backups to James Vandenberg.  The Hawkeyes haven’t disclosed who’ll be returning kicks against the Golden Eagles.
