"We just continued to build a relationship," Clemmons said. "They said they liked what they saw and were excited about me coming out for a visit."
Clemmons is scheduled to arrive in Iowa for his official visit on Thursday and stay until Sunday. He still is waiting for a scholarship offer from the Hawkeyes.
"We haven't really talked more about that," the 6-foot-1, 185-pound lead guard said. "I'm hoping we talk about it on the visit and I get an offer."
"It was really nice," Clemmons said of his Northern Illinois trip. "I really enjoyed my time with all of the coaches and the players. The campus was really nice, too."
Clemmons verbally committed to Eastern Michigan in August before reopening his recruitment a week later. The Scout.com two-star prospect said the Eagles were still in the hunt for his services, but he wanted to see what else was available to him before solidifying his decision.
Clemmons has not scheduled any more visits beyond his Iowa trip.
"I'm not sure I'll take any more," he said. "If I do, then it will probably be to Western Kentucky."
Iowa has a verbal commitment from point guard four-star Mike Gesell in the '12 class. The Hawkeyes could conceivable fill one of their two remaining open scholarships with a No. 1 as this year's projected starter, Bryce Cartwright, will be a senior.
