"I don't know yet," the Class of 2014 in-state athlete said. "I just went with linebackers."
The 6-foot-1, 195-pound Ferch earned Elite All-State honors as a running back last fall. He rushed for 2,264 yards and 33 touchdowns and also excelled at linebacker for State Center, West Marshall High. He was named academic all-district.
"I would do either one," Ferch said about his college position.
Sunday's junior day represented Ferch's second stop at Iowa.
"It was nice," he said. "I got to meet some other juniors that were there. I knew some of them. I got to know the coaches a little bit better. The game I went to, I didn't really talk to the coaches."
Ferch spoke with Hawkeye linebacker coach Levar Woods and strength and conditioning coach Chris Doyle for an extended period of time, he said.
"(Woods) talked about what it takes to be a good linebacker at Iowa," Ferch said.
"I know more now than they did," Duncan said. "It helps a lot because they've been there. They just said to keep everybody involved and to keep talking to everybody. They just said to stay in contact with everybody because you never know what will happen."
Duncan Ferch said he is hearing from Iowa, Iowa State and Nebraska. The Cyclones are in the most consistent contact with him.
"I've gotten to know my recruiting coach really well, Shane Burnham," Duncan said. "I like him a lot. He's really easy to talk to."
Ferch will attend Iowa State's junior day on Feb. 16. The Cyclones are not sure at which position he fits, he said.
"It would be nice to play with (his brothers in Ames) but it won't make me go there just because they are there," Duncan Ferch said.
Ferch, who reports running the 40-yard dash in 4.58 seconds, scored 37 points in a recent basketball game. He qualified for the state track meet in several relays as a sophomore.
"I'm going to go to a lot (football) camps this summer," Ferch said. "We work out as a team a lot, too, doing plyometrics. I'm trying to get faster and stronger."
Ferch, who still awaits his first scholarship offer, will continue to play on both sides of the ball as a senior. Whether it's linebacker, running back or somewhere else, he's working towards the next level.
"On offense, I can make guys miss or run them over if I have to," Ferch said. "I feel like on defense I do a good job of reading my keys."
