Thompson began the visitation process with a post Christmas visit to Texas. However, he didn't decide after the trip and subsequently took two more trips.
Last week, for their game against Missouri, Thompson visited Iowa State. His familiarity with Iowa State comes from assistant Fred Quartlebaum who recruited Thompson out of high school when the coach was at UNC.
Thompson said the official visit to Iowa State went well but he continues to look around. On Saturday, he made an official visit to hometown Northwestern.
"I'm going to make a decision by the end of the weekend or by Monday or Tuesday," Thompson said Saturday morning.
