Wednesday, Indiana offered the 6-foot-6, 255-pounder when he was in Bloomington taking part in a team camp. The Columbus North High product reported an offer from Iowa on Sunday, the same day he camped with the Hawkeyes.
Shoaf said Ball State was the first school to offer him a scholarship. He felt good about his chances of receiving an opportunity from the Hoosiers.
"I had a feeling that it would be coming," Shoaf said. "They kind of led on that it might be. It's a good surprise but not much of a surprise."
Shoaf's trip to Iowa on Sunday represented his third time visiting the Hawkeyes. He was at last season's Michigan State game and attended a junior day in February.
"I'm looking for a school with a good atmosphere for football that also provides a top education," Shoaf said. "I want to be on a team that wants to play together. Two of the main things with Iowa is that they sell out every game and have a great atmosphere and they've also got a good engineering program.
"I'm looking to go into civil engineering. My dad has owned a construction company for 30 years. I might go into construction management or maybe architecture."
Shoaf said he does not have a favorite school right now and is keeping his options open. He hopes to make his decision by August 6th, when his high school begins practice.
Shoaf, a Mormon, leaves Thursday for Utah. He will be attending a camp at BYU on Monday and Tuesday.
"I feel like it's possible that I'll receive an offer there as well," Shoaf said. "From there, I'm calling it quits for the rest of the summer unless something comes up. I need to be at practice working with my team."
Shoaf said the Hawkeyes told him he was fundamentally sound.
"That's one thing that I pride myself on," he said. "I also fly around between the whistles to tell you the truth."
Shoaf was basking in the light of his Iowa offer before the Hoosiers stepped forward on Wednesday.
"It's 45 minutes from home, which is a big thing," Shoaf said of Indiana. "They have great facilities. They have a great coaching staff. It's a fun atmosphere to be in. They want to play football.
"They're definitely in the middle of a rebuilding stage. They're trying to find the guys they need to rebuild with. Then they're going to try to turn the program around."
