McGuire, a 6-3 guard from Elkhart, Ind., chose the Flames over Evansville. He averaged 16.3 points, five rebounds and 2.5 assists last season.
“The whole coaching staff has been committed to me ever since I came to their elite camp over a year ago and (they) stressed the importance of having me there,” McGuire said. “Also with being there, I believe I will become the best player I can be, and they are willing to help me get there. I saw them play a year ago, and I can now see how much they have improved which shows how the coaches are getting their players to reach their potential.
“Most importantly, I have a great relationship with the whole coaching staff and players as well. I’m proud to say I will be a part of the UIC family.”
McGuire is UIC’s first Class of 2013 commitment.
