IOWA CITY, Iowa (AP) – Iowa’s Marvin McNutt is one of the nation’s best receivers, a 6-foot-4 perfect fit for the Hawkeyes. McNutt might have trouble finding open space if Iowa can’t find anyone else dangerous enough to keep defenses honest. Junior wide receiver Keenan Davis is among the inexperienced players the Hawkeyes are leaning on after losing 12 starters from a year ago. Davis had just 11 catches in 2010 while playing behind McNutt and Derrell Johnson-Koulianos. He’ll get his first career start on Saturday when Iowa opens the season at home against Tennessee Tech. Iowa coach Kirk Ferentz says Davis has shown potential as a big-play receiver. He says the next step for Davis is to prove it on Saturdays.
