Reiff, who was one of Iowa's first offers of the class, said he had an immediate connection with the Iowa staff.
"It was great," he said of his first contact. "I had a good relationship with all the coaches. We really got along well."
Iowa doesn't usually dip into South Dakota, with only one player on the roster, but somehow, Riley's name found its way to Iowa City.
"I think some people around here told them about me," he said. "I guess they got some film on me and offered."
Being in South Dakota doesn't mean Riley wasn't aware of the Iowa program, however.
"I know stuff about it," he said. "(Former Hawkeye and Minnesota Viking) Chad Greenway is from around here. I knew they had great tradition too, it seems like they're on TV every Saturday."
Reiff said he wanted to get a decision out of the way early, and focus on his senior season. His junior year was obviously good enough to net some premiere offers, but Reiff isn't really focused on stats.
"I couldn't really tell you my stats," he said. "(My team) made it to the quarterfinals of the playoffs."
Reiff, who was on an unofficial visit to Nebraska, had offers from Nebraska, Iowa, and Minnesota.
