Willies said he met with Hawkeyes head man Kirk Ferentz for 90 minutes on Friday.
"He told me about his family and how he grew up," the 6-foot-4, 195-pounder said. "He told me what coaching life has been like for him. I told him stuff about me. It just kind of went on like that."
At the end of the conversation, Ferentz offered the Rock Island High product a scholarship.
"They liked the way that I played and they thought that I would fit into their offense," Willies said. "I play aggressive and I'm going to work as hard as I can."
The Badgers hosted Willies for a visit two weeks ago.
"Wisconsin wants me to come back up," Willies said. "They're coming down here in the spring to watch me work out. Nebraska, I haven't really talked to them too much."
Willies said that he will visit Iowa State on Thursday.
"I'm looking for somewhere that feels like home," he said. "The main thing is that they want me there. I want to feel like I can spend at least four years there."
Willies received that vibe at Iowa on Friday.
"It was great," he said. "They really made me feel welcome. They all took the time to talk to me and they all kept telling me how much that they wanted me there. They just really made me feel like I was wanted there."
Willies reports a top time of 4.4 seconds in the 40-yard dash. He also runs the hurdles, anchors the 4x100 and leads off the 4x400 for the Rock Island track team.
Willies' combination of size and speed has caught the attention of BCS level programs.
"It's really picked up in the last couple of months," he said. "I want to go where they pass it and they want to get me the ball. I'll commit really whenever I feel like that's where I want to be and I know that's the school."
Willies, who wants to study engineering in college, is intrigued by what else might be out there for him.
"I'm open," Willies said. "I guess you could say Iowa is the favorite, but I want to wait to see what other options I might have. It seems like it's really been picking up a lot and bigger schools have kept coming along. So, it seems like waiting would be the best."
